Mel Gibson was all smiles at UFC Fight Night 42 ... flanked by some pretty hot ring girls.
Gibson was front and center for the Henderson/Khabilov main card in Albuquerque. Mel hung out with some of the fighters, include Clay Guida and Cub Swanson.
With his criminal record expunged in the whole Oksana Grigorieva thing ... Mel seems care-free.
As for the main bout ... we're guessing he was not rooting for the Russian.
