Scarlett Johansson scarpen.jpg Well, it looks like Woody Allen's decided to give everyone on earth at least one reason to see his upcoming movie Vicky Cristina Barcelona - a steamy lesbian sex scene between Scarlett Johansson and Penelope Cruz!

According to an insider who spoke to PageSix.com, the scene promises to be "extremely erotic. People will be blown away and even shocked. Penelope and Scarlett go at it in a red-tinted photography dark room, and it will leave the audience gasping."

The two also allegedly get it on with Javier Bardem, who plays Penelope's husband in the film.

Yeesh, sounds like this movie's gonna have more action than a whole night of Cinemax - not that we're complaining, mind you!
