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!"
