WASHINGTON: Jennifer Lopez and Marc Anthony have renewed their wedding vows away from the public eye in Las Vegas. The duo, who tied the knot over four years ago, repeated their promises and commitments to each other at Caesars Palace’s Forum Tower Penthouse at 3:15 am on October 12.

They decided on their renewal ceremony, witnessed by two friends, after having spent the night at Pure Nightclub, a representative for the hotel confirmed.

“It was totally a spur of the moment thing,” People magazine quoted a source as saying.

“They decided around 12:30 in the morning that they wanted to do it and started calling for ministers.”

Both singers, who attended Criss Angel’s Cirque Du Soleil show Believe, were thought to be in the city to mark Anthony’s birthday last month — later supposed as a disguise.
