Prominent Hollywood personality George Clooney and his girlfriend Sarah Larson have split an year of romance, a report has said.
The 47-year old American actor, director and producer was single again after an year of dating with Larson, 'People' magazine said on its website, quoting a source.
The pair initially met in Las Vegas nearly four years ago, when Larson, a onetime
winner, was a cocktail server at The Whiskey Bar. But it wasn't until they met for the second time in June 2007 in Las Vegas that sparks flew.
"We do not comment on George's personal life," Clooney's representative Stan Rosenfield was quoted as saying.
Larson, 29, and Clooney made their public debut together at the Venice and Deauville film festivals last September.
Later that month, the twosome were injured in a motorcycle accident.
Earlier this year, Larson accompanied Clooney to the Oscars the first girlfriend ever to go with him to the event.
Though there was speculation that Clooney would end his longtime bachelorhood, in March the actor shot down rumours of an engagement, the website added.
