Friday night, Jennifer Lopez and Marc Anthony mugged with Criss Angel following his show in Vegas. The following day, the twosome worked their own magic. The superstar couple completed Marc’s 40th birthday celebrations by renewing their wedding vows at approximately 3:15 a.m. Sunday in the Forum Tower Penthouse at Caesars, sources tell E! News. Lopez, 39, and Anthony got hitched in her L.A. backyard on June 5, 2004, just five days after Anthony’s divorce was complete. (Those historically minded readers may remember that Anthony also renewed his vows with first wife Dayanara Torres in 2002, two years before their split.) No official comment from the happy couple about the redos, but let us be the first to say: Cheers!
