Katy Perry Talks 'Wedding Nails,' Britney Spears' Teeth

'I brush my teeth all the time. I wanted them to be, like, Britney Spears white,' Perry responds to fan's question in YouTube Q&A.

Two weeks ago, [artist id="3274550"]Katy Perry[/artist] took to YouTube asking her fans to submit questions for a Q&A session. And they did, flooding the site with more than 20,000 queries about, well, pretty much everything.

On Tuesday (July 27), Perry took a stab at actually responding to a fraction of them in a 30-minute interview that finally gave us answers to such burning questions as "What is your favorite food?" (beets and arugula), "What girl would you like to kiss?" ("Natalie Portman — she's hot and smart"), and, perhaps most importantly, "Would you ever consider posing for Playboy?" ("I would probably say no").

She also fielded more than a few inquiries about her personal life, including one about her upcoming marriage to comedian and former VMA host Russell Brand, and whether or not the couple planned on having children one day.

"We are excited to get married, of course. And I think, in marriage, when you're picking a partner, one of the things to keep in mind is 'Will he be a good baby daddy?' And he'll be perfect," Perry said.

She then revealed that at her wedding, she plans to keep things a bit demure, at least when it comes to her nails.

"I'm kind of a nail aficionado and freak ... I think for my wedding I'll do what is called 'wedding nails,' where it's traditional and pretty," she laughed. "I don't know if I'd want, like, Oompa Loompas on my nails while taking my pictures."

Very important to know. Perry was also asked by a fan if there was one thing people didn't know about her that would be shocking to find out, and, ever the champ, she responded with two of them.

"I'm pretty much an open book ... well, my boobs are real, just wanted to cover all that," she said. "And I brush my teeth all the time. I wanted them to be, like, Britney Spears white. I used to grow up seeing her music videos, like, 'What does she do? Does she get a new set of teeth all the time? They're so white!' "

Perry also said that she's blown away by the public's response to her smash hit "California Gurls," especially all the parody videos that have popped up in its wake. She watches as many of them as she can, and she's still looking for more.

"I actually welcome them. I do kind of take myself seriously when it's appropriate to, with different songs ... but I know that 'California Gurls' is just a fun song, and I think that if people are making parodies of your song, you've made it," she explained. "And I think we're only a couple of states away from having all 50 states in the U.S.A. to be parodied ... I love that stuff. I welcome it. I actually want to see more of it."
