More than four years after they tied the knot, Jennifer Lopez and Marc Anthony renewed their wedding vows early Sunday morning at Caesars Palace in Las Vegas.

The ceremony — which took place at the newly renovated Forum Tower Penthouse — was officiated by Reverend Steven Smith; two friends served as witnesses.

New York Mets player Carlos Beltran and his wife Jessica also renewed their vows, a source tells Usmagazine.com.

Lopez and Anthony began their night with dinner in a private room at Bradley Ogden at Caesars Palace. Then they played craps in the main room, where both Anthony and Beltran won, says the source.

Afterwards, they headed to the Pussycat Dolls show, followed by Pure Nightclub, where the group had reserved three tables. A source tells Us Lopez and Anthony started asking around for the minister while they were at Pure around 12:30 a.m. and then headed up to their room to meet the minister at 3 a.m.

Beltran and his wife renewed their vows first; then, at about 3:30 a.m., Lopez and Anthony had their own ceremony.

Says the source: “It was very intimate and sweet. They both talked about how much they love each other. The word ‘forever’ was used a lot!”

(The source says twins Max and Emme were down the hall in the same suite, being watched over by Lopez’s parents.)

After the ceremony ended around 4 a.m., the minister left, and the butler brought in a bottle of Dom Perignon Rose champagne, says the source. The group toasted and moved to the area near the piano in the suite, where they talked and laughed until early in the morning, the source adds.
