Alessandra Ambrosio

Spring has sprung for some of our favorite snap-happy celebrities, which in some cases meant pretty flowers — like for Emmy Rossum and Izabel Goulart — but also spelled trouble for those with allergies (see: Karlie Kloss cuddled up sick in bed). Otherwise healthy fashion fixtures like Rachel Zoe and Jenni Kayne spent some time in the garden, while Brad Goreski gave his best Vogue pose in front of a street mural in NYC. Alessandra Ambrosio and Adriana Lima blew kisses to the camera while shooting for Victoria's Secret in LA, and their fellow Angel Doutzen Kroes had fun with cashmere during a day of modeling in Amsterdam.

Now that major events like Fashion Week and award season have wrapped up, it's time for celebrities to get back to work — or, in some cases, vacation. This week, Nicole Richie and Jessica Alba made the press rounds to promote their respective projects, while Alessandra Ambrosio and Ashley Tisdale hit the beach. Kim Kardashian showed love to a cute little puppy, and Ian Somerhalder hit the red carpet with internet sensation Grumpy Cat. Down in Austin, TX, for South by Southwest, Selena Gomez got to visit with family, and Nikki Reed snapped silly photos with her husband, Paul McDonald.

Alessandra Ambrosio kept it casual in Brentwood yesterday, after a busy few days of modeling bikinis and cocktail dresses. The Victoria's Secret Angel sported a pink sweater, light jeans, and a pair of pastel-frame shades while running an errand in the LA neighborhood.

Earlier this week, Alessandra launched Victoria's Secret's 2013 swim collection with fellow brand ambassadors Karlie Kloss and Candice Swanepoel. Later in the day, they hosted a live Twitter chat for fans, then stopped by the Beverly Center store for a meet and greet. The trio celebrated a hard day's work at the celebrity-packed VS swim line launch party in Beverly Hills that night, where Alessandra put her new Instagram account to use — see more celebrities using Instagram here!

Alessandra Ambrosio and a Peter Pilotto-clad Candice Swanepoel linked up with Karlie Kloss, who donned a sexy Cushnie et Ochs dress, to celebrate Victoria's Secret's new swim collection at a party in Beverly Hills last night. The girls posed together and snapped pictures with Steven Tyler at the star-studded bash. The celebrations were well-deserved after a jam-packed day of promotional duties. Alessandra, Karlie, and Candice donned colorful bikinis at the VS launch earlier that morning, where we chatted with them about their favorite vacation spots and got tips on choosing the best bikini for your body.

While Karlie, Candice, and Alessandra had fun celebrating the brand's new 2013 swim line, their fellow Angel Miranda Kerr was not so fortunate. Miranda wore a neck brace yesterday while running errands in LA after reportedly being injured in a car accident on Monday.

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."
