Katy Perry: Andy Makes Her Cream, Idol Makes Her...Mean?

Hit-making "I Kissed A Girl" singer reveals her lust for Mr. Samberg and dishes on her A.I. guest judging gig

If Andy Samberg were single, Katy Perry would so be trying to make him jizz in his pants.

The perky pop singer can't get enough of the Saturday Night Live funnyguy.

"Oh...my...God! I just saw Andy Samberg," Perry, 24, stuttered to me on last night's VMA red carpet. "I know he's going out with someone, but he's so hot.

"Oh...my...God," she said again. "I'm going to freak out. I'm already creaming in my panties. Oh my God!"

Ms. Perry finally did get to meet Samberg. Keep reading to find out what happened. Plus, she dished on why she had to get brutally honest when she was a guest judge for American Idol...

A source tells me that one of Perry's handlers introduced her to Samberg, 31.

"Katy was really cute. She was sort of speechless," the source said. "And then she was like, 'I have the biggest crush on you.' She turned so red."

Meanwhile, Perry said she'd love to do more guest judging on American Idol. She recently joined Simon Cowell, Randy Jackson and Kara DioGuardi for a round of Los Angeles auditions.

She said she had to break at least one person's dream for musical stardom. "I was like, I just don't really think this is your gig," Perry said. "I said, 'Maybe you should start singing in front of other people and see what they think. They might think the same thing.' "

As for Ellen DeGeneres joining the show, Perry opined, "I think she's talented and creative...You need some balance, and Ellen will bring that. Maybe she won't be the most musical opinion, but she's a genuine person."
