Jennifer Lopez officially changed her last name to Affleck on a Nevada marriage license after tying the knot with actor Ben Affleck.

The power couple eloped and got married in Las Vegas on Saturday, Jennifer confirmed in an Instagram post.

She shared a post-coital photo of herself in bed looking satisfied with a smile on her face.

Bennifer were married just three months after becoming engaged, and nearly 20 years after Ben, 49, proposed to Jen, 52, for the first time in 2002.

The marriage license identifies Jennifer Affleck and Benjamin Geza Affleck as a married couple, NBC News reported.

"It was the best possible wedding we could have imagined," J-Lo wrote on her personal website, On The JLo, and in her newsletter, according to PEOPLE. She shared photos and videos of herself and her new husband.

This is the fourth marriage for Jennifer, who shares 14-year-old twins, Emme and Maximillian, with her third husband Marc Anthony. They were married in 2004 and divorced in 2014.

She was also married to Ojani Noa from 1997 to 1998 and Cris Judd from 2001 to 2002.
