Scarlett and Penelope's steamy kiss

First looks at Woody Allen's latest film Vicky Cristina Barcelona, which premieres at Cannes, depicts a steamy scene where stars Penelope Cruz and Scarlett Johanson lock lips, hinting fans are in for one of Allen's sexiest movies yet.

Vicky Cristina Barcelona tells the story of two young American women, Vicky (Rebecca Hall) and Cristina (Johansson), who travel to Barcelona for a summer holiday. Vicky is sensible and engaged to be married; Cristina is emotionally and sexually adventurous. In Barcelona, they're drawn into a series of unconventional romantic entanglements with Juan Antonio (Javier Bardem), a charismatic painter who is still involved with his tempestuous ex-wife Maria Elena (Cruz).

Besides the steamy pash between the two screen sirens, there is reportedly a scene where Bardem, Johansson and Cruz take part in a sexy threesome.
