Miley Cyrus says there's no way she's going to be locking lips with Katy Perry at this Sunday's Teen Choice Awards.

The 23-year-old "I Kissed a Girl" hitmaker recently said in an interview that she was hoping to snag a same-sex smooch onstage with the 15-year-old Cyrus in the spirit of the infamous Madonna-Britney Spears kiss.

"No thanks," the Hannah Montana star told me yesterday with a laugh. "She sang on my record. So I think she's kind of getting back at me, because she was doing harmonies and backgrounds."

Meow!

Cyrus has been on a nonstop promotional campaign to support her new hit album, Breakout, and her upcoming gig as the host of Teen Choice.

Will she ever slow down?

Probably not, but she says she'd love to eventually take a break from Hollywood to go to college.

"I was online the other day looking at colleges," Cyrus said. "I want to go in London. I'd like to do fashion and then photography."

But she's still got time to think about higher education. She doesn't even turn 16 until November.

"I'm into just kind of chillin'," Cyrus said about her upcoming birthday. "I'm into having just a good ol' pool party or, like, [going to] the beach with a couple of friends. I don’t want to feel like I have to entertain the whole time."

That's not the only big event in November. Her animated movie with John Travolta, Bolt, hits theaters on Thanksgiving. Will she and Mr. Travolta sing together on the soundtrack? "I would like that," Cyrus cooed. "I mean I think that would be so cool. Oh my gosh!"

Another legend I had to ask about was one of my idols, Dolly Parton. The country music icon has appeared on Hannah Montana as Hannah's Aunt Dolly.

"I will tell you," Cyrus said, "Dolly is like the nicest person ever. On our set, from people that clean our dressing rooms at night to the top producers, she gave them hats and signed every one of them. It was like 500 hats!"

As much success as Cyrus has had and as much as she loves what she does, she's actually discouraging her 13-year-old brother from getting into show business...well, at least for now.

"He's really talented, really good at the drums," Cyrus said. "But he's, like, 13. So, you know, he's not ready for it yet. He's like, 'I don't want to start as young as you did in the business.' I'm like, 'Yeah, I agree.' I think he should, like, finish high school and stuff."

Sounds like good advice from a showbiz veteran.
