Couple Alert: Natalie Portman & Sean Penn?

I’m having trouble digesting this one, but here goes. Star magazine is claiming that Sean Penn was spotted at the Sunset Tower Hotel Bar with Natalie Portman “constantly touching each other.”

A spy told the tabloid, “They went to a bank of elevators that only goes to the spa or to private rooms. They came back about 45 minutes later, and that’s when I saw them making out.”

Sean seems like a loose cannon, but Natalie?  I guess I shouldn’t act so incredulous. Stranger things have happened. Especially when it concerns celebrities.
