Ananova:

We've heard of oddities related to celebrity weddings.

But it seems Jennifer Lopez and Marc Anthony like making theirs a group affair.

They've said "I do" again - with another couple in tow.

According to People, J.Lo and Marc renewed their vows in Las Vegas and were joined by New York Mets' Carlos Betran and his missus, Jessica, for a joint ceremony.

A source has said: "Carlos gave his wife a specially engraved ring and gave Marc and Jennifer special rings as gifts.

"Carlos and Jessica renewed their vows first, then Jennifer and Marc went."

This all went down in one of the newly renovated penthouses at Caesars Palace hotel.

The ceremony was apparently witnessed by 12 people and afterwards everyone toasted with Dom Perignon champagne.

Cheers.

And thanks for the invite, guys.
