Jennifer Lopez and Marc Anthony, her husband of four years, after two nights of club-hopping in Vegas, including Criss Angel’s new Cirque Du Soleil show Believe, in a spontaneous, spur of the moment moment, renewed their wedding vows at 3:15 a.m. in a small ceremony at casino Caesars Palace’s Forum Tower Penthouse.

 Doubling the fun, the Anthonys’ with Lopez looking beautiful in a black, joined New York Mets outfielder Carlos Beltran and his wife Jessica in a joint vow renewal ceremony officiated over by Vegas minister Rev. Steven Smith.  The couples exchanged rings, watched by 12-witnesses, though Lopez’s parents missed the ceremony, since they were watching over the babies.

 The newly re-married couples celebrated toasted each other over a bottle of Dom Perignon champagne.
