Singer Jennifer Lopez and actor Ben Affleck have finally tied the knot, after getting a licence to get married in Las Vegas.

The marriage licence was issued by Clark County in the state of Nevada dated Saturday, July 16, according to document details posted online by the county clerk’s office.

It came after Lopez announced their engagement in April, after the celebrity couple rekindled a romance almost 20 years after they first got together.

Lopez announced their marriage on Sunday (US time) in her newsletter for fans with the heading “We did it”. Lopez initially made their engagement public in April on the same newsletter, On the J Lo.

“Love is beautiful. Love is kind. And it turns out love is patient. Twenty years patient,” wrote Lopez in a message signed Jennifer Lynn Affleck.

Lopez wrote that the couple flew to Las Vegas on Saturday, stood in line for their licence with four other couples and were wed just after midnight at the Little White Chapel, a chapel that has a drive-through “tunnel of love”.

Lopez said a Bluetooth speaker played their brief march down the aisle. She called it the best night of their lives.

“With the best witnesses you could ever imagine, a dress from an old movie and a jacket from Ben’s closet, we read our own vows in the little chapel and gave one another the rings we’ll wear for the rest of our lives,” Lopez wrote.

“Stick around long enough and maybe you’ll find the best moment of your life in a drive through in Las Vegas at 12.30 in the morning in the tunnel of love drive-through with your kids and the one you’ll spend forever with.”

News of their nuptials first spread Sunday after the Clark County clerk’s office in Nevada showed that the pair obtained a marriage licence that was processed on Saturday.

The marriage licence filing showed that Lopez plans to take the name Jennifer Affleck.

Representatives for Lopez and Affleck declined to comment.

Lopez, 52, and Affleck, 49, famously dated in the early 2000s, spawning the nickname “Bennifer”, and starred together in 2003’s Gigli and 2004’s Jersey Girl. They rekindled their romance last year.

In 2002 Affleck gave Lopez a 6.1-carat pink diamond engagement ring, but they abruptly called off their wedding in 2003 and split up a few months later.

Affleck married Jennifer Garner in 2005, with whom he shares three children. They divorced in 2018.

Lopez has been married three times before. She was briefly married to Ojani Noa from 1997 to 1998 and to Cris Judd from 2001 to 2003.

She and singer Marc Anthony were married for a decade after wedding in 2004 and share 14-year-old twins together.

“In the end, it was the best possible wedding we could have imagined. One we dreamed of long ago and one made real (in the eyes of the state, Las Vegas, a pink convertible and one another) at very, very long last,” she wrote to fans.

“They were right when they said, ‘all you need is love’. We are so grateful to have that in abundance, a new wonderful family of five amazing children, and a life that we have never had more reason to look forward to.”
