Ryan Phillippe returned to the club scene early Tuesday morning following his split with Abbie Cornish.

Arriving at Los Angeles hotspot Teddy's around midnight, the actor, 35, who was dressed in all black, kept a dark beanie pulled low over his face as he drank a beer with his pal.

"Ryan did not look happy," says a source, who tells the actor and a pal did one loop around the club before leaving at 12:45 a.m.

Even though girls "definitely noticed him," the witness says "he looked a bit somber."

On Monday, a rep for Phillippe told Us: "He called her to end the relationship as they'd simply grown apart. She flew into town to move out as he asked her to do."
