After a night at Pure Nightclub in Vegas, the duo renewed their vows at Caesars Palace’s Forum Tower Penthouse with two friends by their side according to the magazine. “It was totally a spur of the moment thing,” a source said. “They decided around 12:30 in the morning that they wanted to do it and started calling for ministers.” In related news, Jennifer Lopez attended Elle Magazine’s 15th annual Women in Hollywood tribute recently. The event paid tribute to the careers of Halle Berry, Jane Fonda, Nicole Kidman, Anne Hathaway, Sigourney Weaver and Isla Fisher.
