Via Just Jared and Inside Edition

The couple split after two years of dating and People.com reports it was actually Keibler who dumped Clooney.
People magazine editor Charlotte Triggs told INSIDE EDITION, "She wants to have children someday and George has famously said that he does not want to settle down and does not want kids. So, she had to end the relationship."
Clooney was photographed over the July 4th holiday weekend with his buddies at his Italian villa in Lake Como, Italy. Keibler was no where in sight. They apparently broke up a few weeks ago but People.com says it was a friendly split.
