It appears that  George Clooney's on-and-off long-running romance with actress Krista Allen is on again, according to the New York Daily News.

Clooney and Allen dated for two years beginning in 2002 when he cast her in Confessions of a Dangerous Mind, his adaptation of the Chuck Burris memoir.

Allen broke it off in March 2004. Clooney dated model Lisa Snowden for a time, then he and Allen got together again in 2006. He moved on to cocktail waitress Sarah Larson but broke off with her last spring.

Whether Clooney, 47, will ever settle down is anyone's guess. Stay tuned.
