Alessandra Ambrosio Bikini Pictures

Alessandra Ambrosio, Candice Swanepoel, and Karlie Kloss donned colorful bikinis to launch Victoria's Secret's 2013 swim collection in LA today. The Angels, all decked out in Victoria's Secret, playfully posed for the cameras in front of a pool as they prepared for a day of promotions. Later in the day, the girls will host a live Twitter chat with fans and take part in a meet and greet at the brand's Beverly Center store. The trek to the photo op wasn't a long one for Alessandra, who has been working on a new VS bikini campaign in Malibu over the past week. She, Candice, and Karlie are all great ambassadors for the sexy swimwear collection since they are all heavily featured in the new Victoria's Secret swimsuit catalog.

Alessandra Ambrosio suited up in a tiny black bikini yesterday to shoot a Victoria's Secret campaign in Malibu. She's been on a weeklong shoot with VS, which has included modeling a rainbow two-piece and meeting up with her fellow Angel Adriana Lima for the cameras. Alessandra will have plenty of time to catch up with her VS model buddies today when she hosts a meet and greet at the lingerie brand's store in Beverly Hills with Karlie Kloss and Candice Swanepoel. She posted news about the Victoria's Secret meetup on her Facebook page, asking fans to take photos with the three beauties. Alessandra wrote, "Hope to see you there for lots of fun and a swimsuit giveaway!"

Alessandra Ambrosio and Adriana Lima were hard at work on the set of a Victoria's Secret photo shoot in LA yesterday. The Angels took turns posing separately, with Adriana hopping on a beach cruiser and Alessandra hitting the sand in a bikini, before taking a few sexy shots together.

The girls have been staying busy with many VS opportunities recently. Alessandra braved the cold weather to model swimsuits earlier this week and linked up with fellow Angel Candice Swanepoel to film a lingerie commercial with director Michael Bay last month. Adriana has been making the rounds to promote Victoria's Secret's new fitness line and seemed excited to reunite with her Brazilian buddy on the beach. She posted a photo of the two of them on her Facebook page, saying "my angel Alessandra Ambrosio."

Alessandra Ambrosio worked a bikini for a chilly Victoria's Secret photo shoot in Venice Beach yesterday. She was decked out in a rainbow Victoria's Secret bikini, but also modeled more cold-weather-appropriate sweatpants and hoodies. Alessandra's dog, Buddha, also got in on the action, posing with his model mama on a bicycle while photographer Ben Watts snapped photos.

Alessandra's been busy with VS lately. She and Candice Swanepoel shot a Victoria's Secret lingerie ad in LA less than a month ago. Alessandra has been keeping busy on many other things outside of the world of VS. She is currently preparing for the launch of her new fashion line, ále by Alessandra, which is due out in Spring 2014.

Alessandra Ambrosio and Candice Swanepoel met up in Miami on Saturday to shoot a sexy Victoria's Secret lingerie commercial with director Michael Bay. The models were joined by fellow Angel Lais Ribeiro as they posed in lacy bras and lingerie against a graffitied building. When we met up with Candice in NYC last week, she teased the commercial, saying that she would be filming the new ad and then jetting off to Brazil. She teased, "I'll probably [be spending Valentine's Day] in Brazil, enjoying the sun and the beach. I feel sexiest on the beach." Candice has been doing plenty of traveling over the past few weeks, including flying to New Orleans to watch the Super Bowl and shooting a Victoria's Secret bikini campaign in St. Barts.

Alessandra Ambrosio captured bikini moments for her social-media fans while relaxing on a beach in St. Barts yesterday. She snapped photos with her phone while splashing in the waves and relaxing on a chaise. Alessandra posted her self-taken bikini snaps on Instagram, including a shot of shells in the water and one of herself tanning her legs. Once she was done taking pictures, Alessandra cooled off by taking a dip and playing with a dog. Although Alessandra's photo-worthy bikini session wasn't part of a planned photo shoot, she later took to the waves in a few more two-piece suits and poses for an upcoming Victoria's Secret campaign. Candice Swanepoel also wore a bikini while working her Angel magic for the camera in St. Barts this week.

Alessandra Ambrosio soaked up the St. Barts sun in her bikini yesterday. The Victoria's Secret model, who wore a rainbow-colored string bikini, unwound on a lounge chair with a copy of People in between dips in the ocean. Alessandra enjoyed some downtime after a weekend spent working for VS on the island. She was spotted sporting a series of skimpy swimsuits during Saturday's beachside photo shoot, which took place just a few weeks after the annual Victoria's Secret Fashion Show aired.

Alessandra is no stranger to sporting a two-piece in front of the cameras, but let us know if you think she has the best bikini body of 2012 in our year-end poll!

Alessandra Ambrosio hit the beach in St. Barts on Saturday to do a photo shoot with Victoria's Secret. It was a lengthy day before the lens for Alessandra, who wore a variety of two-pieces during her time in the sun. She arrived on the island Saturday, and after lunch with friends at the Eden Rock, hit the beach, or what she dubbed her "office for the day." The getaway to St. Barts is Alessandra's last job of the year. 2012 has been a big one for her. In addition to expanding her family with fiancé Jamie Mazur and their daughter, Anja, with the birth of baby Noah, Alessandra also had the honor of wearing the Fantasy Bra during this year's Victoria's Secret Fashion Show. No stranger to showing skin, Alessanda's posing has her ranked among the top bikini moments of the year.

Alessandra Ambrosio kept busy yesterday with a bikini session in Malibu and an afternoon stop at Mr. Bones Pumpkin Patch in West Hollywood — see all the celebrities getting into the Halloween spirit! The whole family — Alessandra, her fiancé, Jamie Mazur, and their kids, Anja and baby Noah Mazur — joined in the hunt to find the perfect pumpkin. Jamie did most of the heavy lifting while Alessandra carried Noah.

At the beach, Alessandra changed into a white bikini for a game of volleyball. She gave us a sneak peek of the fit frame that we'll see more of when this year's Victoria's Secret Holiday Fashion Show airs on Dec. 4. She'll reunite with her fellow Angels Miranda Kerr and Candice Swanepoel, as well as musical guests Justin Bieber, Rihanna, and Bruno Mars.

Alessandra Ambrosio hit the beach in Malibu yesterday with a group of girlfriends and her daughter, Anja Mazur. The pals posed for photos, with little Anja showing off her own posing skills in front. Alessandra and Anja, along with dad Jamie Mazur, welcomed a new member, baby Noah, to their family just two months ago. Alessandra didn't wait long before throwing on her two-piece and hitting the sand. Yesterday, Alessandra wore a bikini under her cutoffs and a tied-up button-down.
