It isn’t just Megan Fox who sizzled at the Transformers movie premiere at LA. Her co-star Isabel Lucas was a scene stealer at the  opening night of the film, looking hot and classy in her Chanel chiffon frock. Playing a slutty bitch in the film, Isabel provided Megan a competition as to who the hottest girl is in robotown. I’d still say it’s Megan, but Isabel’s catching up fast.

This Australian actress isn’t new to the glare and controversies of Hollywood. She already became a hot item when she hooked up with Entourage star Adrian Grenier and Transformers co-star Shia Labeouf. Oh, I mean she was the girlfriend of Adrian when she hooked up with Shia. The Transformers stars were involved in a DUI incident during the filming of the movie, where Isabel was riding shotgun when Shia crashed into another car at 3 am. Adrian wasn’t so happy about learning his girlfriend partying with Shia. So soon after a little hypocrisy of still appearing sweet together, the two broke up. It was almost too safe to assume that it was Adrian who dumped Isabel, but TMZ revealed it was actually the other way around.

Aside from being torn among Shia and Adrian, Isabel was also seen hanging out with Jared Leto lately. Popsugar.com reports that the possibly new couple “had big smiles on their faces on Sunday when they paid a visit to an LA grocery store to pick up flowers and a few Easter baskets.” Anyway, this Hollywood hottie is also climbing up the fashion ladder as she has been invited to be the special guest of Chanel at their Haute Couture Show in Paris that’s happening on July 7th. Hmm… So, a fashion career and a new boytoy? Not bad! Find out more about this hottie here and more Hollywood celebs and scandals.
