Ben Affleck wedding: Fans are upset with J.Lo about a detail

People online have mixed opinions about the fact that Jennifer Lopez changed her name after her wedding to Ben Affleck — and some don't seem happy at all.

Jenny from the block changed her name after marrying Ben Affleck in Las Vegas recently, and some commenters have decided they need to hit back.

Some people reacted strongly to her new name after the couple's marriage documents were shared on Twitter by Buzzfeed reporter David Mack. The name change was later confirmed by Jennifer, who signed an email to fans saying, "With love, Mrs. Jennifer Lynn Affleck."

Someone wrote: "I refuse to call him J.Aff." Our question: Who is looking for it?!

A third asks: "Wait, why don't both parties take each other's last name. Much more romantic." Ben Lopez? Not bad.

Anyway, fans, take it easy. In 2003, on "Ben & Jen: A Dateline Special ," the singer was asked if she would change her legal name and stage name, to which she replied, "I think I'm going to stick with Jennifer Lopez, but My name will be Jennifer Affleck, obviously."

So J.Lo will legally be called Jennifer Affleck, but when people scream at her concerts, she's J.Lo, not J.Af - as far as we know...
