Stars in Bikinis
We've been watching reality TV long enough to remember when Heidi Montag was a sweet, normal, pretty teen from Colorado. These days, after some nips and tucks and one very public recent plastic surgery binge, Montag has completely transformed herself into a generic-looking Femme-Bot. She debuted her new implants with a bikini bash in Las Vegas on April 10, 2010.
"90210" star AnnaLynne McCord took her hunky "Twilight" boyfriend (Kellan Lutz) for a swim during a trip to St. Martin on April 10, 2010. But, um, we're kind of distracted by McCords bikini (do two vertical strips of fabric qualify as a bikini?). God bless her for having a beautiful body, but we're not sure we could ever have the nerve to go out in public like that.
During a trip to the West Indies with husband David, Victoria Beckham covered up on the beach on April 3rd. Whether she forgot her sunscreen, her waxing appointment, or simply didn't want her bottom in the tabloids, the skinny star conservatively tied on a pareo up to her waist, and covered her face with some shades and a big floppy hat. Come on, Vicky, show a little skin!
Serena Williams enjoyed a beach day in Miami on April 1st. The tennis champ wore a racy green lingerie-inspired bikini and matching black glove, which she's been wearing out a lot lately.
Kim Kardashian hit a beach in Costa Rica (with boyfriend Reggie Bush, not pictured) on March 7, 2010. She wore no shortage of bikinis during her stay, including this white string style.
Her name was Lola... wait, no, her name is Paris Hilton. Who else would pose so provocatively on the balcony of her Rio de Janeiro hotel? Hilton celebrated Valentine's Day by giving the paparazzi and eyeful.
Blake Lively wasn't afraid to bare her famous curves during a day in Miami on February 8, 2010. "Gossip Girl" co-star Chace Crawford also enjoyed the sun nearby.
Singer Lily Allen doesn't believe in matching bikinis. The star showed off her feminine curves in Auckland, New Zealand on January 14 in a gray tied-front bandeau top and black and white scalloped-edge bottom.
Lindsay Lohan strolled through the streets of St. Barths on January 3, 2010 in a barely-there black bikini and black platform heels. Linds, we hate to break it to you, but wrapping a scarf around your neck isn't exactly a legitimate way to make a bikini into an outfit. We're just sayin!
Alexandra Burke showed off her six pack abs in a red hot bikini while on holiday vacation with friends in Barbados on December 28, 2009. The British pop-star and winner of the fifth series of The X Factor looked more toned than ever in her teeny, strapless suit.
