J. Lo and Marc Anthony Renew Vows

Less than a year after the birth of the couple's first children, singers Jennifer Lopez and Marc Anthony renewed their vows in a dual ceremony with New York Mets outfielder Carlos Beltran and his wife, Jessica, according to People magazine.

"Carlos gave his wife a specially engraved ring and gave Marc and Jennifer special rings as gifts," according to a source who witnessed the event. "Carlos and Jessica renewed their vows first, then Jennifer and Marc went."

The ceremony took place at the Caesar's Palace recently renovated Forum Tower Penthouse, which reopened on Saturday. Lopez and Anthony were the first guests to stay in the suite since the reopening.

A source said the ceremony came after a successful night in the gambling arena.

"They were both winning at the craps table and Marc kept saying that it was going to be a lucky night," the source told People.

The source said the ceremony went on with only one hitch: The event was initially supposed to take place outside, but had to be moved due to cold weather.

The couple's twins, Max and Emme, were born in February. Lopez and Anthony were married in 2004.
