She doesn’t turn 33 until Friday (April 11) but Alessandra Ambrosio was all about celebrating her big day a bit early while out in West Hollywood last night (April 9).

Fresh from her adventures in Australia at Sydney Fashion Week, the supermodel mommy headed over to 1OAK Nightclub where she met up with partner Jamie Mazur and a group of friends for a pre-birthday shindig.

And as always, Alessandra was the center of attention in her cut-out little black dress with leopard print Christian Louboutin sandals.

Prior to opening Alex Perry’s Sydney Fashion Week runway presentation (her first appearance at the event), Ms. Ambrosio told press, “I get butterflies so I try to meditate before opening a show. I love the collection, it’s so cool and I love the denim textures and all the lace and transparency.”
