Britney Spears Bikini Pictures

Britney Spears slipped into a bright blue bikini to spend the holiday weekend by the pool with her boyfriend, David Lucado, at a resort in Rancho Palos Verdes, CA. On Sunday, the couple cooled off in the water before changing into comfy clothes and taking a spin around the property in a golf cart, showing some sweet PDA along the way. They went for a romantic stroll through downtown Palos Verdes while shopping for antiques on Memorial Day — and Britney tweeted her thanks "to the brave men and women who serve this country," along with a throwback photo of herself in a patriotic ensemble to celebrate.

Britney has been sticking close to home in LA lately, balancing family fun with multiple new projects. She hit the stage earlier this month to host KIIS FM's Wango Tango concert and has reportedly begun recording her eighth studio album this week with executive producer Will.i.am. She has also been spotted frequenting dance studios and rehearsal spaces around town — likely in preparation for her Las Vegas residency at Planet Hollywood this Fall.

Britney Spears hung out in the sun with friends in Malibu, CA, yesterday, working on her tan in a striped bikini after taking off a black cover-up. She's back in LA following a quick trip to Las Vegas over the weekend. Britney and her boyfriend, David Lucado, checked out a Cirque du Soleil performance, dined at Meatball Spot, and reportedly caught Shania Twain's Still the One show during their getaway. They may become regulars in Sin City if rumors that Britney signed a two-year contract with Caesars Palace earlier this year prove to be true.

Britney Spears wore a bikini yesterday while hanging out in sunglasses. She shared a picture with her Twitter followers along with the caption, "Having some fun in the sun. . . don't want summer to be over!" Britney was able to make the most of the season by taking her sons, Sean and Jayden, as well as her fiancé, Jason Trawick, off for a fun vacation. Last month, the foursome snuck off to Hawaii — and a snap from their getaway made our roundup of the Summer's best celebrity pictures! Despite their fun, the last few months have been full of work. Britney toured the country with The X Factor taping the show's upcoming season, and we'll be able to check her out on the small screen starting Sept. 12.

Britney Spears shared a sweet picture of herself in a bikini with her sons, Sean Preston and Jayden James, in Hawaii yesterday. She added, "Getting ready for some pool time! Having a blast." Britney was later spotted heading to her hotel pool with a shirtless and very tan Jason Trawick and her boys. Britney and her fiancé traveled to the islands with Sean and Jayden on Monday, and they've been soaking up the sun ever since. The foursome celebrated the Fourth of July together yesterday and captured the holiday fun with a sweet snap of them all wearing leis. They were just a few of the many stars — from Zac Efron to Jessica Alba to Heidi Klum — marking Independence Day on the beach.

Britney Spears was in a bikini yesterday to play at the pool of her Rio hotel with boyfriend Jason Trawick and her sons Sean Preston and Jayden James. Her mom Lynne was also in a two-piece for the splashing session, and the girls stuck together while Jason horsed around with Jayden and Sean. The Spears clan is in Brazil as Britney takes her Femme Fatale tour through South America. They arrived in the city over the weekend, with Sean and Jayden not wasting any time before exploring the town. Britney's dad Jamie took the little ones to the beach, where they were seen running on the sand and testing the waves. It'll be back to work soon for Britney, as she'll take the stage tonight at Rio's Apoteose and will be in Sao Paulo this weekend.
