Don't expect Katy Perry to mimic Lindsay Lohan's manicure when she walks down the aisle with comic Russell Brand -- the singer says she will have tasteful "wedding nails" on her big day.

"I'm kind of a nail aficionado and freak," Perry explained in a recent YouTube Q&A session, according to MTV News.

"I think for my wedding I'll do what is called 'wedding nails,' where it's traditional and pretty. I don't know if I'd want, like, Oompa Loompas on my nails while taking my pictures."

While Perry, who is known for her rainbow-colored ensembles, cupcake bras, and crystal-embellished candy pants, hasn't revealed what kind of dress she'll don when she says "I do," the singer will certainly be wearing white -- at least as far as her smile is concerned.

"I brush my teeth all the time," she said. "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!'"

The YouTube Q&A session was based entirely on questions submitted to Perry by her fans.

And true to form, she answered everyone honestly -- even if it meant giving a little TMI about her ta-tas.

"I'm pretty much an open book," said 25-year-old Perry. "Well, my boobs are real, just wanted to cover all that."
