Weeks earlier, the Magic Mike actor brought Lazoore to the Samsung Galaxy S III launch in L.A. "She was close by Joe's side all night," an eyewitness tells Us Weekly of the June 21 bash. "They seemed to be a cozy couple."
Prior to stepping out with Lazoore, Manganiello had been falsely linked to single star Demi Moore, 49, whom he met at the L.A. afterparty for Adam Sandler and Andy Samberg's comedy That's My Boy. "There is 100 percent zero truth," Manganiello told Ryan Seacrest of their alleged pairing. "I don't care to talk about my personal life unless it is to shoot down rumors that I'm dating someone."
