Jennifer Lopez paid homage to her new husband Ben Affleck’s 51st birthday by sharing a sweet Instagram post on Tuesday.

‘Dear Ben … Happy Birthday. I love you!’ penned the singer — who recently turned 54 — while giving fans a glimpse at their low-key celebration.

In the short clip, Jennifer was in the passenger’s seat of Ben’s car as they sang along to Sam Cooke’s Wonderful World with the windows rolled down.

‘Everything is going well in his life. He is happy and content,’ a close friend of the actor added.

Weeks earlier, Jennifer rang in her 54th birthday with a party that Ben threw together at their new $60M mansion in Beverly Hills — which they snapped up in June after over a year of house hunting.

Jennifer shared photos from the lavish shindig with fans who follow her monthly On The JLo newsletter.

‘Thank you all for the birthday love. Here’s a lil peek into my party,’ began the star.

She continued: ‘Ben hosted it at our new house with our closest family and friends. All the kids were there, it was a gorgeous day full of sunshine and perfect for a pool party!!’
