Jennifer Lopez and Marc Anthony’s Secret Celebration

People has learned that the two stars discreetly renewed their wedding vows.

The celebration took place on Sunday (October 12) at Caesars Palace in Las Vegas, followed by a party at the nightclub Pure.

Two eyewitnesses were there to see Reverend Steven Smith give his blessings to Jennifer Lopez and Marc Anthony.

"It was totally a spur of the moment thing. They decided around 12:30 in the morning that they wanted to do it and started calling for ministers," said a source close to the couple.

In addition to the ceremony, Lopez and Anthony made the most of their time in Vegas and saw a Cirque du Soleil show and the magic show Believe, starring Criss Angel.
