More than four years after saying "I do", Jennifer Lopez and Marc Anthony secretly renewed their vows in Las Vegas according to People. Witnessed by two friends, the duo renewed the vows at Caesars Palace's Forum Tower Penthouse at 3:15 a.m. Sunday after a night at Pure Nightclub. "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."

All of this right after the February 2008 birth of their twins, Max and Emme.

Vegas, Baby!
