Are they having a hot hookup???

Eva Mendes and Madonna's ex Guy Ritchie looked very friendly at the 2009 GQ Men of the Year Awards in London last night - not only did they share a table, but Eva kinda sorta ran her hand through Guy's hair!

Better watch your back, Eva... the Material Girl is gonna be pissed! And doesn't Eva have a longtime beau (George Gargurevich)?

She and Guy look mighty friendly in this pic!
