*Jennifer Lopez and her husband of four years, Marc Anthony, renewed their wedding vows in Las Vegas early Sunday morning in a spur of the moment decision.
"They decided around 12:30 in the morning that they wanted to do it and started calling for ministers," a source told People.com.
Two friends were on hand to witness the occasion, which took place at Caesars Palace's Forum Tower Penthouse at 3:15 a.m. Sunday. The service was officiated by Rev. Steven Smith.
Before renewing their vows, the couple hung out at LAX Nightclub and The Bank, and also took in Criss Angel's new Cirque Du Soleil show Believe – all under the guise that they were in town celebrating Anthony's birthday from last month.
