AS THE WORLD TURNS' Mark Collier (Mike) put seven wannabe models to the acting test on the UPN reality show AMERICA'S NEXT TOP MODEL. And each scene ended with a steamy kiss.

"Not a bad day," smiles Collier. "It's easy for me to say that, I've been doing this for a while. When I first started, it was very uncomfortable to be rolling around [with someone]. I remember a scene in my acting class where I was in my underwear with this girl and I was very uncomfortable."

So Collier could relate when one model -- Catie -- wasn't into kissing him. "It was pretty funny. She was 18 years old. She was like, 'Yech. I don't want to kiss some guy I don't know.'" Collier was contacted by AMERICA'S NEXT TOP MODEL to do the dramatic, back-from-the-dead scene with the models in front of acting coach Tasha Smith-Arqese. "I would tell them to relax a little bit or try to calm them down, but I couldn't give them any pointers," he notes. "I couldn't tell them anything about acting. I'm no authority to be judging people's acting. I was just there to do the scene. We found out during [the process] that quite a few of them want to be actors. Shandi and April were the best. There's no doubt about that."

While Collier appeared in the episode (which originally aired Feb. 17), he first saw the on-air show with the rest of America. "There was a lot of stuff that was left out, and a lot of stuff they showed that didn't really happen," he reveals. "Some of the girls made a line funny and I laughed at what they said. But they made it look like I was laughing at their acting. I would never embarrass them or embarrass myself by breaking in the scene. But that's the way they made it look. I wish there was a little more of the Camille [scene], because she did change a lot of the lines. It was really funny, actually. And at the end they made it look like I chose [April], which I didn't."

Collier is now interested in the show's outcome. "I'm not a reality show fan," he reveals. "It's weird, but I may end up watching next week now. There was a girl on the show, Shandi, that I really liked. She was cool and down-to-earth. I want her to do well."

Many of Collier's ATWT co-stars tuned in to his reality show debut. "Michael Park (Jack) just walked in the room quoting my lines from [the show]," groans Collier. "Everyone's been making fun of me, but that's okay, I can take it."
