Bruce Willis Making Out with Courtney Love? WTF?!

Gatecrasher is reporting Bruce Willis celebrated turning 52 last week with a makeout session with the broken-faced Courtney Love.

The strange couple were spotted in "flagrant 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.

Another source says Willis carried on the rest of the evening without Love by his side. -- The actor's rep declined to comment, while Love's spokesman described the interaction as "a quick hi, and then they went their separate ways."

-- Holy nastiness Batman! Bruce was making out with goddess Drew Barrymore at Prince's Golden Globes party in January and now Courtney Love? What's Bruce thinking?!
