Scarlett Johansson and Penelope Cruz have taped a steamy lesbian sex scene for their latest flick.

The Hollywood stars share a red-hot scene in a red-lit photography dark room in Woody Allen’s ‘Vicky Cristina Barcelona’, according to U.S reports.

“It is also extremely erotic. People will be blown away and even shocked,” an insider told the New York Post.

“Penelope and Scarlett go at it in a red-tinted photography dark room, and it will leave the audience gasping.”

The stars later have a threesome with co-star Javier Bardem, who plays Cruz’s husband.
