Wilson Phillips talk 'Bridesmaids' cameo

After two hours of unexpected emotional upheaval, even more unexpected intestinal evacuation and some of the decade's biggest belly laughs, "Bridesmaids" sends audiences out on a high note thanks to a surprise cameo from Wilson Phillips and an rocking performance of "Hold On!"

But how exactly did Carnie Wilson, Chyna Phillips and Wendy Williams land this cush comedy gig? "They called us -- it was as simple as that," Carnie tells PopWrap. In addition to getting their name back out into the public sphere, Carnie admits that saying yes was a no-brainer because "these producers have made some of my favorite movies so we knew it would be a smart thing to be involved with. But we had no idea how funny the movie was going to be."

A fact that truly caught Carnie by surprise as (over)shares with PopWrap, "when [Melissa McCarthy's character] sh** in that sink – I peed in my pants. I know that’s gross, but I pissed myself."

Ironically that moment only validated Carnie's choice to join the project. "I spent a lot of years laughing with my girlfriends, and this movie really reminded me of the beauty of female friendship. Plus, they used to make me pee my pants too."

Thanks to the movie, Wilson Phillips is riding high on wave of recognition they haven't experience since "Hold On" came out in 1990 -- a turn of events they still marvel at to this day.

"When I wrote that song, I was 19 years old and was really at a crossroads in my life," Chyna tells PopWrap. "I knew that if I didn’t make some really significant changes in my life, I’d end up being another Hollywood statistic. So those words – “hold on for one more day” – were literally what kept me going because if I had to look at everything at once, I don’t think I would have been able to do it. But if I said, 'just for today, I’m going to see my therapist. Just for today I’m going to not smoke a cigarette. Just for today I’m not going to hang out with that crowd,' then I was able to handle it."

"I never imagined writing down words that were meant to help me, would help so many people along the way and become this iconic song."

So where do the ladies go from here? "We’re in the process of recording a CD right now," Chyna reveals. "It's a cover album of all Mamas & Papas & Beach Boys hits -- then, hopefully we can come out with an original record. That's the goal."

And while music is at the top of their to do list, Carnie sees a second upside to her "Bridesmaids" cameo: "I want to be in the sequel," she says. "I could be Melissa McCarthy’s cousin and we can be crazy together. I don’t care who I’m playing, I just want in!"
