Oh, yes! Our baby Christian Siriano is on fire, ladies and gentlemen.

Since taking home the grand prize two months ago, the Project Runway season four winner has created several "major" ensembles for Victoria Beckham, outfitted Kimberly Locke for an American Idol performance, and now the chic little man has been tapped to create a 15-piece collection for Puma.

Recently, London babe Estelle wore one of the designs -- a ruffle-neck dress made from deconstructed Puma tanks -- to her record release party, which Sirano attended.

On the piece worn by Estelle, the designer told People magazine: "For me it's really exciting because it's great to work with an artist that wants to be more creative and more fashion forward. That's why I love her. I mean how fabulous is she?"

Meanwhile, Siriano will be appearing alongside Nina Garcia in tonight's episode of Ugly Betty. If you want a sneak peak of the episode, click here.
