Hollywood's most eligible bachelor is here to stay! Now that Stacy Keibler has gotten just enough street cred for being George Clooney's girlfriend of more than a year, it looks like she is ready to call things off with her much older beau.

A split between these two has not been confirmed just yet, but has pretty much been inevitable since they began dating in 2011, as we all know George isn't the settling-down type. But it seems there's a lot more than that behind the reason Stacy is so over him (and it's not just the godawful beard, either).

"They have little in common," a source tells Us Weekly. "She likes to go out and have fun. She's been feeling the age difference." In case you were counting, that age difference is 18 years, with Stacy in her prime at 33 and George, still beautiful, but starting to show his age at 51.

Another source tells the mag that friends of George and Stacy don't get along, and that the "end is near" in just a matter of time.

Ever since George's divorce in 1993, he is notoriously known for not wanting to marry again, and has been in several long-term relationships that never led to another walk down the aisle. So we can't necessarily feel bad for Stacy if things aren't going to work out — she had to see it coming. But of course, we don't blame her for jumping at the chance to spend almost two years in George's arms....

How long do you think George and Stacy will last?
