Mickey Rourke planted a wet one on his good pal, stylist to the stars Giuseppe Franco, on Thursday -- and it looks like he liked it!

Despite his camoflage trousers, Mickey couldn't hide from our eyes when he and his friend had a rather intimate goodbye after lunching at Cafe Roma in Beverly Hills.

Mickey seems like he was in good company with Giuseppe. The hairdo guru is besties with Arnold Schwarzenegger and Sylvester Stallone -- and is always hanging at Cafe Roma with the action stars. Maybe the hairdresser can help fix Mickey's mangy mane?!

See these two in slo-mo action ...
