We spotted Alessandra Ambrosio on her way into STK steakhouse in Los Angeles on Wednesday to celebrate her 32nd birthday. The model showed off her fabulous figure in a slim fitting white mini dress.

The model posted a message on Facebook this morning with a photo of herself clutching a bunch of pink balloons: "Thank you so much for all the lovely birthday wishes! You have made my day even more special! Xx."

The Brazilian model is one of the exclusive Victoria's Secrets Angels. Her co-Angel Miranda Kerr made headlines this week after rumors circulated she was fired from the lingerie giant.

Ambrosio made cameos in the movie "Casino Royal" and HBO's "Entourage." She has been engaged to businessman Jamie Mazur since 2008, and they have two children - daughter Anja Louise, 4, and son Noah Phoenix, 11 months.
