Jennifer Lopez changed her name to Jennifer Affleck following her surprise Las Vegas wedding to now-husband Ben Affleck.

The “Jenny From the Block” singer reintroduced herself with the new moniker Sunday in her “On the JLo” newsletter, in which she signed off, “With love, Mrs. Jennifer Lynn Affleck.”

While that may have been an informal change for the sake of the announcement, the newlyweds’ marriage certificate, obtained by Page Six via Clark County records, shows that she plans to use “Affleck” legally going forward.

Page Six confirmed Sunday afternoon that Lopez, 52, and the “Argo” star, 49, tied the knot the night before in Sin City. Hours later, the “Selena” actress confirmed the news and provided all the details about their wedding, which included their combined five children.

“We barely made it to the little white wedding chapel by midnight,” she revealed. “They graciously stayed open late a few minutes, let us take pictures in a pink Cadillac convertible, evidently once used by the king himself (but if we wanted Elvis himself to show, that cost extra and he was in bed).”

Lopez added that she wore “a dress from an old movie” to exchange vows and that she and Affleck “gave each other the rings we’ll wear for the rest of our lives.”

The couple met in 2001 on the set of their much-maligned movie “Gigli” while Lopez was still married to her second husband, Cris Judd.

About a year later, Affleck proposed, but they split before making it down the aisle.

The pair reunited 20 years later, shortly after the “Dear Ben” singer split from fiancé Alex Rodriguez in early 2021.

“We did it. Love is beautiful. Love is kind. And it turns out love is patient. Twenty years patient,” Lopez gushed Sunday.
