Alessandra Ambrosio was back on the beach in Malibu on Monday, busy soaking up the California sun for more sizzling Victoria's Secret bikini shots.

Tuesday morning she joined fellow VS Angels Karlie Kloss and Candice Swanepoel for a photocall for the Victoria’s Secret Celebrates the 2013 Swim Collection & Angels and Artists Swim Video Series.

The three supermodels will then appear from 5-7pm Pacific time (today -- that's an hour from now for those of you in the area!) at the Victoria's Secret store in the Beverly Center shopping mall in Los Angeles for a meet & greet with fans.

Yesterday Alessandra tweeted, "Come take a photo with me, Karlie Kloss and Candice Swanepoel tomorrow at Victoria's Secret at the Beverly Center from 5-7pm! Hope to see you there for lots of fun and a swimsuit giveaway! xx."

And today she wrote, "Hope to see you all tonight at Victoria's Secret at the Beverly Center! I'll be there from 5-7 with some fellow angels so be sure to come by if you are in the area! xx."

We're in.
