Stacy Keibler and George Clooney have reportedly ended their relationship after dating for nearly two years.
"Stacy called it quits. She wants to have children and a family someday. She knows where George stands on that," a source close to the pair toldPeople.
"They talked and they quietly stopped being a couple several weeks ago."
However, Keibler -- who participated on the second season of Dancing with the Stars and will host Lifetime's upcoming Supermarket Superstarsreality series, which premieres on Monday, July 22 -- and Clooney are reportedly trying to keep things friendly and civil between them.
"They talk every day. They were friends before they started dating and they'll be friends after. It was a friendly [breakup]," the source explained.
In addition to wanting different things down the road, Keibler, a 33-year-old actress and model, and Clooney, a 52-year-old actor, apparently struggled with their hectic work schedules.
"They haven't seen each other in a while and they've both been working so much, so in recent months, they've started growing apart," another source told People, adding that Keibler looks forward to traveling.
The couple was reportedly last spotted together in March in Berlin and recently spent the July 4 holiday apart.
Lifetime announced it had orderedSupermarket Superstars in August and that it will feature aspiring food product inventors pitching their original ideas to a panel of industry experts in the hopes of launching their creation nationally in a major grocery store chain.
