Sean Penn may be married to Robin Wright Penn, but she’s getting old and wrinkly, and probably isn’t interested in doing much of anything anymore, so it seems Sean has decided to have a little fun on the side.

Star Magazine is reporting that the actor was seen on a date with Natalie Portman at the Sunset Tower Hotel’s Tower Bar last week, where they spent their time “constantly touching each other.”  After dinner, Natalie and Sean were spotted going off to either the spa or private rooms for a 45 minute rendezvous.  A source claims that she then caught the pair making out on the hotel’s terrace.

Natalie and Sean have a 21-year age difference between them, and Sean has been married to his wife since 1996, though the pair have separated twice in the past.
