Jennifer Lopez and Marc Anthony renew their wedding vows

Washington, October 13 (ANI): Celebrity couple Jennifer Lopez and Marc Anthony have renewed their wedding vows away from the public eye in Las Vegas.

The duo, who tied the knot more than four years ago, repeated their promises and commitments to each other at Caesars Palace's Forum Tower Penthouse at 3:15 a.m. 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," the source added.

Both singers, who attended Criss Angel's new 'Cirque Du Soleil' show 'Believe', were thought to be in the city to mark the occasion of Anthony's birthday last month - later supposed as a disguise. A source, who spoke to the couple, said: "(Marc) said they were in town for his birthday and they wanted to celebrate." (ANI)
