UFC stud Tito Ortiz celebrated his 37th birthday with baby mama Jenna Jameson by his side at XS in Steve Wynn’s Encore on Sunday night. While preparing for the celebration, Ortiz tweeted, “Getting ready, this is going to be the best night of my life.”

The on-again-off-again-on-again couple, who are the parents of twins Jesse Jameson and Journey Jette, arrived at the hotspot after midnight and were seated at a private table overlooking the dance floor. Ortiz was dressed to the nines in a black pinstripe vest, black slacks, a black dress shirt and a white tie, while the blonde bombshell and former porn star wore skin-tight black pants, a shear top and fingerless leather gloves.

The pair, looking happier than ever, enjoyed champagne at their table decorated with black-and-silver balloons. DJ Pizzo kept the party going until the early hours of the morning. Before XS, Ortiz, Jameson and 18 of their friends dined at the new Old Homestead Steakhouse in Caesars Palace, feasting on Osetra caviar, shellfish platters, Dover sole, porterhouse steaks and side dishes.

Vegas DeLuxe wishes the Las Vegas nightlife regular “Happy Birthday” — and on his actual birthday, to boot! Thanks to Danny Mahoney of XS for his photos.
