Ah-ha! I knew she looked different but I thought she was merely maturing. Wrong. Amid reports that she had plastic surgery, Bristol Palin sat down with Us Magazine to clear up any lingering rumors about her fresh new look.

In the new issue on stands Wednesday, the 20-year-old reality TV star, who turned heads at the White House Correspondents' Dinner in April, revealed, "I had corrective jaw surgery [in December 2010] ... Yes, It improved the way I look, but this surgery was necessary for medical reasons ... so my jaw and teeth could properly realign ... I don't obsess over my face."

Former Alaskan Governor Sarah Palin’s daughter, who appeared on season 11 of the hit series 'Dancing With the Stars,' recently signed a deal to star in a reality series for Bio, in which she and son Tripp will move to Los Angeles to live with actors Chris and Kyle Massey and work for a charity.

If you remember the presidential campaign, you will recall Palin had 2-year-old Tripp with Levi Johnston, who apparently still has a career, as evident by the just-released cover of his new book, the appropriately titled 'Deer in the Headlights.' Check it out below.
