A source says of the two, "They have little in common. She likes to go out and have fun. She's been feeling the age difference."
Another source notes that George's friends don't really get along with Stacy's and adds, "The end is near. It's a matter of time."
Of course, this is the same thing that was being said a year ago, so we'll have to wait and see. It is also US Weekly reporting this and they're right up there with the National Enquirer as far as bullshit gossip news is concerned. Take this with a grain of salt.
