Well, we didn't see this one coming! Reports are claiming that longtime friends Sean Penn and Charlize Theron have taken their friendship to a new level! The two were spotted together spending the holidays in Hawaii at Sean's vacation home and arrived back at LAX on the same plane! Hmm.... these two are spending an awful lot of time together! But a source says they are just friends. Looks like we will just have to keep an eye on these two and see if this is the real deal!
