Is Gorgeous George back on the market?

GEORGE CLOONEY has parted ways with his girlfriend of about a year, SARAH LARSON, a source tells People magazine.

Although longtime bachelor Clooney has dated numerous women over the years, his relationship with the cocktail waitress he met in Las Vegas was perhaps more public than his previous ones. She was a common fixture on his arm at Hollywood events, even accompanying him to the Oscars last February.

George's rep, STAN ROSENFIELD, tells ET: "We do not comment on George's personal life."
