Last night at Studio 54 in MGM Grand, the legendary nightclub welcomed Jenna Jameson and Tito Ortiz as he hosted his Official UFC 84 After-Fight Party. Directly following Ortiz’ fight, the notorious UFC star arrived with his beautiful girlfriend in tow and large entourage of family and friends by his side at the Vegas hot spot. Looking cute and deeply in love, the adorable couple was mobbed by fans as they approached the red carpet. Jenna playfully posed with her man, whispering  “I love you” and exchanging kisses.  Immediately after the red carpet, Ortiz and Jameson went straight to Studio 54’s VIP skybox. The pair caused a stir inside as club-goers flocked the area to get a glimpse of the beautiful couple.   Jameson and Ortiz along with friends, family and fans partied all night long drinking champagne and dancing to the beats spun by DJs Mick Boogie and Roktakon.
