Stacy Keibler is reportedly about to become George Clooney's latest ex-girlfriend. The New York Daily Newsreported that the actor's relationship with the former WWE star is on the brink of collapse.

A source told the paper that Keibler, 32, is "breaking down" all the time and constantly checks to see if George has sent her any text messages. The insider added, "George is being really distant and pulling away from her. She wakes up every morning and doesn't know what's going to happen."

The couple, who have been dating for just over a year, are currently working in separate cities. Stacy is in New York preparing to host Lifetime's Supermarket Superstars while George is in Oklahoma filming August: Osage County with Julia Roberts and Meryl Streep.

If they do split, this relationship would be in line with the length of Clooney's recent ones. George dated Italian actress Elisabetta Canalis from July 2009 to June 2011. Prior to that, he was with cocktail waitress Sarah Larson for about a year.
