Jenna was with a few friends -- one of whom looks like Jenna would ... if she ate three square meals a day. The porn queen was all smiles as she waited for a cab, even giving photogs a wave as she sped away.
Recently, Jenna's been telling people she hopes that fellow blonde Scarlett Johansson will portray her in a still-in-the-works biopic. Only problem is Scarlett's peeps tell PEOPLE she hasn't been approached at all -- and if she were, she wouldn't be interested.
Just the thought of Scarlett as a porn star is pretty good.
