Lindsay Lohan Kisses Biz Partner

Lindsay Lohan keeps calling him just a business partner/dear friend, but photos say otherwise.

LiLo was swapping spit over the weekend with Greek restaurateur Dennis Papageorgiou at Bouzoukia nightclub in Athens. He's the money behind LOHAN ... the new club he and Lindsay opened in Athens Saturday night.

Most people shake hands to close a deal. Lindsay is ... different.
