Whether they've gained or lost weight or gone under the knife, a lot of times celebrities don't look the same. While some choose to admit they've gone under the knife, others remain elusive when asked. Reality TV stars, however, will sometimes get their nips and tucks in front of the camera—no secrets there!
Heidi Montag famously underwent 10 surgeries in one day to alter her appearance, while Kim Zolciak-Biermann has admitted to having a tummy tuck after suffering a hernia. Nicole "Snooki" Polizzi received lip injections and posted behind-the-scenes pictures from her time in the plastic surgeon's chair. "Making my lips look fabulous for 2016! #mommytouchup #noshame," she wrote.
Real Housewives of Atlanta star NeNe Leakes has been more than candid about her plastic surgeries, admitting, "If anything falls, I pick it up." She has opted for a breast lift, rhinoplasty and liposuction, the latter of which was shown on her Bravo show.
