Plaza, wearing a hot Dolce & Gabbana navy mini dress, talks about kissing Seth Rogen at the LA premiere of "Funny People."

Is Seth a good kisser?

"Totally! We make out on top of a car! I describe kissing him kinda like riding a roller coaster," she says. "It's scary at times, really fun, and then I throw up a little. In my mouth. Off camera, though. That's not in the movie. Maybe for the DVD."

We like this girl.
