What happens in Cabo no longer stays in Cabo.
Bravo is taking viewers along for a one-of-a-kind vacation with celebrity hairstylist Larry Sims on Invite Only Cabo, a new docuseries that finds Sims and six of his pals on vacation together in Cabo San Lucas, Mexico.
"I just couldn't say no to it," Sims tells ET. "I've been approached about doing reality for quite some time now, and I just wanted to do something that was organic, and I actually would've, without cameras, taken my friends on a vacation and thrown them in a house and, you know, here we are."
Sims, who's responsible for Victoria Beckham's iconic bob and counts Tracee Ellis Ross and Gabrielle Union as clients, invited six of his friends on a four-week getaway down south -- but here's the catch: none of the guests knew each other!
"Everybody was themselves," Sims says. "I actually had never gone on vacation with any of these people, and I've known these people, some of them, for over 20 years. So, a lot of it was my first time experiencing being out of the country in some place, for four weeks, with any of them. So, I was surprised."
"I'm still friends with everybody that's on the trip," he reveals, before starting to laugh. "They aren't."
"My whole intention was to make sure that I showed everybody that there were more things that they had in common other than just me," he adds. "I was kind of hoping to cultivate friendships that would be lifelong, as I've had really long relationships with everybody. Didn't work out that way."
Well, that might be because a lot of drama goes down in Cabo. As Sims notes, a lot can happen in 48 hours, so just imagine what occurs over four weeks' time.
"There was a love triangle that was really hot and steamy," Sims teases. "And crazy ��� It was one of those that, was it better to do this or, you know, did you guys cause more trouble than anything else?"
Sims describes the season as an "adrenaline rush," both for the cast and for viewers.
"I'm excited to see it all," he admits. "The thing about it is, it's really full of emotions. You get the anger parts of it, and you get the heart, and you get laughter, and you get compassion for one another. You get passion, frustration. You get hangovers. So, it's sort of like, you know, the full gamut of emotions."
As for the cast member to keep an eye on, Sims says that's Emily Moses. The Australian beauty is heavily featured in the trailer for picking off her press-on nails at the dinner table!
"We all got a little crazy in us, don't we?" Sims asks.
"We are not cheating you guys out of a good time," he finishes. "I can tell you that much."
Invite Only Cabo premieres on Sunday at 9 p.m. ET on Bravo. Check out our full chat with Sims, which includes a Cabo-themed hair tutorial, in the Facebook Live below.
