Special Forces: World’s Toughest Test is back for season 2 — and it did not disappoint Us.

Brian Austin Green and Blac Chyna are among the 14 perfectly-cast celebrity contestants attempting to complete military training led by ex-Special Forces operatives on the Fox show. During the wildly entertaining Monday, September 25, premiere, the unlikely duo got off to a rocky start, with the Beverly Hills, 90210 alum and the reality TV personality, whose real name is Angela White, arguing over the temperature in their living quarters.

“It’s hot to you,” Chyna said repeatedly to the actor after he questioned why she needed a blanket.

In a confessional, Green admitted that he can “absolutely be a pain in the ass,” telling the camera: “I enjoy poking and prodding people every once in a while.”

“The f–king attitude on her. It’s crazy,” the actor told Chyna. “How did I end up in the bunk next to you? My God.”

Chyna replied, “Chill out and leave me alone.”

Later on in the episode, Green accused Chyna of giving him unnecessary “dirty looks.”

“Huh? What are you talking about?” she responded.

After Green said, “I’m just saying,” Chyna questioned Green’s intentions.

“I’m from D.C. Don’t play with me. I’m not the one. … Stop playing with me. I’m not playing with you,” she said. “I don’t know if you’re playing or if you’re serious.”

“Of course I’m playing, I’m never serious,” he claimed. “I don’t want to create any drama, I don’t want to make you feel bad at all.”

Chyna made it clear she doesn’t find Green amusing. “You’re not going to ever make me feel no type of way. I’m going to let you know that right now. But carry on though – because you’re so funny and all that, right?” she said.

After Chyna stormed out, Savannah Chrisley — yes, she’s on this show too — asked, “What the heck happened?” JoJo Siwa subsequently checked in on Green, causing Us to applaud the casting department for the umpteenth time.

While several contestants including Tyler Cameron, Nick Viall, Kelly Rizzo, Robert Horry, Erin Jackson and Bode Miller didn’t get much screen time on Monday’s episode, Tara Reid couldn’t escape the staff (despite how hard she tried).

After becoming the first star to quickly fail the first task — walking across a bridge suspended 340 ft above a freezing river — she was caught trying to sneak in cigarettes. While she handed over two packs when confronted, Reid claimed she didn’t know she had a third pack in her other pocket.

“Don’t f–k with me next time,” one of the operatives told the actress to which she replied, “I didn’t know it was in there!”

Siwa also came under fire with the staff for her playful demeanor, but the third moment that made Us thankful this show exists was Tom Sandoval‘s introduction. The Vanderpump Rules star — who took on the competition in the aftermath of his affair with Raquel Leviss — didn’t impress the team from the beginning, with the staff calling him a “mess” and mocking his voice during the initial inspection.

“These past few months have been the darkest moments of my entire life. Sandoval has become Scandoval,” the former SUR bartender said in a confessional with a straight face. “I’m here because I want to get punished.”

Special Forces: World’s Toughest Test airs on Fox Mondays at 9 p.m. ET.

Carl Radke and Lindsay Hubbard sought professional help to work on their problems ahead of their breakup, a source exclusively tells Us Weekly.

“They had actually seen a counselor. But Carl didn’t think it was a good way to start their forever together,” the insider says, telling Us that “Carl had major fundamental issues before the wedding and wanted to take an honest look at them.”

One of the toughest tests for the former couple stemmed from Radke’s sobriety, per the insider. “Sobriety was a big issue for him,” the source adds. “Lindsay had become sober, but then incorporated drinking back into her lifestyle.”

Hubbard, 37, was sober from the end of 2021 to spring of 2022 to show solidarity for Radke, 38, who has been alcohol-free since January 2021. While Radke exclusively told Us in February that he “fully” supported Hubbard “having a glass of wine with her aunt or having a Loverboy with whomever” his feelings seemed to change with time.

“He was nervous about their future together without figuring things out,” the source says, noting, “Things were not resolved between Carl and Lindsay as the wedding was approaching.”

Us confirmed last month that Radke called off his engagement to Hubbard with cameras rolling for Summer House season 8.

“His intention was not to break up with her, he only wanted to address their relationship and it went south,” the insider tells Us, adding, “It wasn’t supposed to be a breakup, but it escalated.”

Since pulling the plug on their romance, Radke and Hubbard “haven’t spoken,” the source says. But the exes have “communicated via text through friends” as “things had to be dealt with around the wedding fallout.”

Earlier this month, Radke emailed his and Hubbard’s wedding guests to inform them that the November ceremony, set to take place in Mexico, was officially off.

Radke expressed sadness in his email, writing, “There have been a lot of false narratives and misunderstandings that have made this all the more painful but sadly at this time we are not moving forward with the wedding. The fact of the matter is Lindsay is devastated and I’m crushed with how all this transpired. I graciously ask for some patience and grace to heal and recover while we navigate this extremely difficult time.”

While Radke seemed to speak on behalf of both him and Hubbard in the letter, the source tells Us, “The email he sent was an issue with her,” pointing out that reports claimed Hubbard was “blindsided” by the message to their guests. However, the insider claims to Us that “Carl has said he did not blindside her” by sending the correspondence.

The former fiancés may not be on the same page about how things ended, but Hubbard has remained steadfast in her claim that Radke was the one who didn’t want to move forward with their relationship.

“My entire life and future was ripped out from underneath me and I’ve had a hard time making sense of it all — with no answers or closure on why,” Hubbard wrote via Instagram on September 14, breaking her silence on the split. “I feel humiliated by how it went down, and simultaneously heartbroken that it happened in the first place. My trust has been betrayed, and coming to terms with that has been difficult for me.”

Hubbard has since bounced back and chosen to focus on her own happiness. Part of that journey included keeping her bachelorette party in the Bahamas. Over the weekend, she celebrated the next chapter of her life with her closest friends.

“I didn’t know this amount of love could exist in one photo. I feel completely overwhelmed by my best friends, and their friendship, love, and strength,” she wrote via Instagram on Monday, September 25, sharing a photo of her squad. “The way these girls have rallied around me the last 3 weeks, held my hand, sat in showers and cried with me, picked me up, never left my side, never let me feel alone, and then took me on a trip — that was originally planned for completely different reasons — and yet still carried on with this trip because it became more important.”

Hubbard concluded: “I’m beyond blessed and thankful for every single one of these girls. This is a story about sisterhood, and I could not do life without them.❤️‍🔥.”

Lindsay Hubbard and Carl Radke have been through it all on Summer House — from breakups to makeups and more — before calling off their engagement in August 2023.

When the series premiered on Bravo in January 2017, Hubbard and Radke were part of the OG cast of Summer House and have since returned for every season. During season 4, the pair attempted to turn their friendship into a romance, but it quickly fizzled out.

Despite their breakup, Hubbard supported Radke following the sudden death of his brother during season 5 of the Bravo show — and as he worked through substance abuse issues, getting sober in January 2021.

The following year, the duo admitted that they were in item. “I’m happy to report, we are dating and things are really good,” Radke exclusively told Us Weekly in January 2022. “We’re very happy. She’s someone that’s been an incredible support and part of my life [for years]. … I mean, we make each other laugh like crazy. I’ve never felt more myself around someone than her. And for me, that’s powerful.”

Us confirmed the pair had gotten engaged in August 2022, while filming Summer House season 7. Hubbard and Radke called it quits, however, before they could walk down the aisle.
