Jessica Alba looks sultry in fuchsia as she shows off a little leg on the cover of the September issue of Cosmopolitan. Despite a reunion lunch with Cash the two are definitely over. In the issue, Jessica keeps quiet about Cash but does dish on Dane Cook and of course, being sexy. Here are highlights:

On her role in Good Luck Chuck and her co-star, Dane Cook:
"I play the biggest dork ever...I've wanted to do comedy my whole career, and Dane really encouraged me just to make an ass of myself."

On when she feels the most confident:
"I probably feel sexiest after the gym, right out of the shower, in my birthday suit."

It will definitely be interesting to see Jessica take on a more comedic role, since we're so used to seeing her kicking ass a la The Fantastic Four and Dark Angel. For more of Alba in Cosmo check out newsstands August 14th.
