Bruce Willis was out partying with friends on his 52nd birthday last Monday, and he ran into Courtney Love, 42, at a club. The two were seen making out like bandits afterwards, although Bruce spent the rest of the night with his buddies:

The unlikely couple were spotted in flagrante canoodle March 19 at the Roxy nightclub on Sunset Blvd. “They were full-on making out,” laughs a witness.

The venue was packed for a 9 p.m. performance by boozy Brit rocker Amy Winehouse.

But it doesn’t look like Rumer, Scout and Tallulah are getting a new stepmom just yet. Another source says Willis carried on the rest of the evening without Love by his side.

Courtney’s rep says they were just saying hi in their unique way.

I wouldn’t be surprised if these two bumped uglies at some point. Maybe they were swapping spit for old time’s sake.
