Jessica Alba: Sheer Sexy at Sirius

Having just made her way to the east coast, Jessica Alba was in promotional mode to kick off the week with a visit to SIRIUS XM Studio in New York City on Monday (August 30).

Looking her usual adorable self in all-black with a sheer top and white kicks, the "Sin CIty" starlet hopped on the mic to answer questions while boosting interest in her new movie "Machete".

Due out in theaters this Friday (September 3), "Machete" is directed by Robert Rodriguez while co-starring Lindsay Lohan and Michelle Rodriguez.

Of the change from her normal roles, Alba told E!, "I was excited to take part in this film. It's like Robert [Rodriguez] at his best, and it's everything you want out of an exploitative film, which is what this film is, but there's a real political and social relevance to the film, and to be part of art in that way is amazing."
