STACY KEIBLER MOVES IN WITH GEORGE CLOONEY!

Shacking up at Chez Clooney! Life & Style can exclusively confirm that Stacy Keibler has moved in with George Clooney, her beau of 15 months. "She's 100 percent moved in," an insider tells the new issue of Life & Style. "She spends her summers with him in Lake Como, Italy, and all her stuff is at his place in LA."

The insider says that while Stacy, 32, maintains a small rent-controlled apartment in West Hollywood, she uses it as a storage space for mementos and personal items. "All her clothes are at George's, and she never goes home."

Cohabitation is a big step for George, 51, but the insider insists The Descendants star is the one doing the pursuing. "Stacy is his dream woman!"
