Jennifer Lopez is getting loud for Ben Affleck’s 51st birthday.
The singer helped her husband ring in his big day Tuesday by posting an Instagram video of the duo singing to “What a Wonderful World” by Sam Cook during a car ride.
The actor sat behind the wheel in a white tee, with Lopez, 54, in the passenger seat wearing a tank top of the same color.
The pair were all smiles crooning, “Don’t know much about the French I took / But I do know that I love you / And I know that if you love me too, what a wonderful world this would be.”
Lopez captioned the footage, “Dear Ben … Happy Birthday. I love you!”
The “Jersey Girl” co-stars have been married since July 2022, celebrating their first anniversary last month.
Not only did the couple honor the milestone by lunching with their blended family and going out to dinner just the two of them, but Lopez teased a new song about their Las Vegas nuptials in her “On the J. Lo” newsletter.
“Midnight Trip to Vegas” marked fans’ first look at the Grammy winner’s upcoming album “This is Me… Now,” which comes more than two decades after her 2002 Affleck-inspired album, “This Is Me…Then.”
She and the “Air” star were previously engaged from 2002 to 2004, going on to marry Marc Anthony and Jennifer Garner post-breakup, respectively, and have children before reconciling in 2021.
Lopez shares twins Emme and Maximilian, 15, with the 54-year-old salsa artist, while Affleck and Garner, 51, co-parent Violet, 17, Seraphina, 14, and Samuel, 11.
In addition to honoring their love story last month, Lopez also celebrated her 54th birthday.
The songwriter’s July festivities included dancing on a table in a backless silver gown and posing for bikini photos in a Valentino suit.
“Birthday mood…all month!!” she captioned party pics via Instagram. “Always a good day when Lola comes to play.”
When the actress went “bare-faced” for her followers on Monday, she said in a Reel that she “just had a birthday and … feel[s] better than ever.”
Lopez, who was “glowing and happy” in the social media upload, clapped back at “bulls–t” rumors she doesn’t use her JLo Beauty products in her daily skincare routine.
