They say you can never go home again, but that apparantly doesn't apply to ex-lovers! 

Poor George Clooney-- he must be so lonely following his breakup with cocktail waitress Sarah Larson that he's gone back to former flame, actress Krista Allen!

According to the Daily News, friends say the two have been quietly seeing each other again.  Krista, 37, and George, 47, began their long-running on-again-off-again romance in 2002, when Clooney cast Allen in Confessions of a Dangerous Mind.   They were soon seen zipping around town on his motorcycle and dated for two years until Krista broke things off in 2004.  Clooney then moved on to model Lisa Snowden, before he and Krista reconnected again in 2006.  When things didn't work out, Georgie began dating waitress and Fear Factor winner Sarah Larson and the rest, as they say, is history.

"Krista has always been there for him," a friend says.  "She admits she just can't get over him....George really loves her."

What's interesting about this love match is that Krista has an 11-year-old son, Jake, from a previous relationship.  Despite  infamously stating that he will never marry and doesn't want kids, friends say this doesn't bother the actor.

"George adores Krista's son," a source says.
