Demi Moore Bikini Pictures

Demi Moore showed off her fit frame when she stripped down to a red bikini while hanging out in Malibu on Sunday. Demi wore a bikini to her friend Harry Morton's home and appeared to be in a good mood while she chatted with a friend. Demi and Harry dated for six months, but the pair reportedly decided to call it quits last week. However, a source said that the two have "remained in regular contact" and are still close friends. Looking forward, Demi is preparing for the release of her newest film, Very Good Girls, which she premiered at the Sundance Film Festival in January.

Demi Moore was in a teeny tiny black bikini on Saturday to hit the beach in the Caribbean. She ran from the water back to her lounge chair, where her shirtless husband Ashton Kutcher was engrossed in the book The Youth Pill: Scientists at the Brink of an Anti-Aging Revolution. The jet-setting couple headed to the islands after a visit to Europe and Texas for the Super Bowl, both of which came after a recent stint in South America. Their time in Brazil gave birthday boy Ashton a chance to flaunt his six-pack by the water while Demi wore another two-piece from her impressive collection.

Demi Moore changed into a different bikini to take a dip in the waters of Rio de Janeiro yesterday. Ashton Kutcher and her daughter Tallulah kept their clothes on to enjoy the sun after he went shirtless for a swim earlier in the week. The couple arrived in Brazil over the weekend so that Ashton could walk the catwalk with Gisele Bundchen for Sao Paulo Fashion Week, though it looks like they've turned the work trip into a relaxing getaway.

Ashton Kutcher, Demi Moore, and Tallulah Willis escaped to their own private island getaway off the coast of Rio de Janeiro on Monday. Shortly after their arrival, Ashton stripped off his shirt and hit the water with Demi following closely behind in her own hot little bikini. The trio arrived in Brazil last weekend prior to Ashton's runway appearance with Gisele Bundchen during Sao Paulo Fashion Week. Demi and Ashton kicked off 2011 with another swimsuit-filled getaway, and they're keeping up that sun-kissed glow straight through the Winter. The loved-up couple may be able to extend their vacation through Valentine's Day, however Ashton might be needed in NYC where his next project, New Year's Eve, is starting production.

Demi Moore spent a luxurious New Year's Eve yachting off the coast of St. Barts in a skimpy Missoni bikini on Friday. She looked toned and tanned in her two-piece with husband Ashton Kutcher by her side. Ashton kept covered up, but the January Men's Fitness cover model revealed his workout regimen of hot Bikram yoga, running, and Krav Maga. He's back in fighting shape and ready to promote No Strings Attached, which opens on Jan. 21. Ashton stars opposite recently engaged mom-to-be Natalie Portman in the romantic comedy that has them casually shacking up and constantly making out.
