Sarah Palin's most famous child "debuted a shocking new look" on the red carpet of the Candie's Foundation benefit gala in New York this week. While her body shape appears pretty much the same, and no one has confirmed that she's had plastic surgery, her face looks way different.

The single mother and daughter of Sarah Palin has landed her own reality show on the BIO Channel, in which she'll move in with fellow "Dancing With the Stars" contestant Kyle Massey and his brother Chris.

Bristol Palin’s face looks slimmer and more heart-shaped while her chin and cheekbones are more defined, giving her an admittedly more “generic Disney star” look. No word on how the single mom slimmed down -- or whether she went under the knife -- but Bristol was happy to tell Us Weekly about her two-year-old son Tripp's latest milestones.

Dr. Norman M. Rowe, a New York plastic surgeon, says the single-mom-turned-abstinence-ambassador appears to have gone under the knife. "The tip of her nose is smaller and more feminine," says Rowe, as quoted by the Daily News. "The bridge of the nose also appears lower. It's not as wide as it previously appeared." Her jawline and cheekbones appear more defined, with the possibility that her chin has been worked on as well.
