Jennifer Lopez Wishes Husband Ben Affleck a Happy Birthday With Adorable Car Sing Along Video

The songstress and her actor husband lip synced an iconic love song in a birthday post.

Jennifer Lopez is expressing her love for hubby Ben Affleck by sharing a sweet snapshot into their private life. 

The "Ain't Your Mama" singer took to Instagram on Tuesday to commemorate Affleck's 51st birthday, and shared an adorable video she recorded while in the passenger seat of their car -- as the birthday boy drove around town.

While on the road, Lopez beamed as she and Affleck lip synced and danced to Sam Cooke's iconic love song "Wonderful World."

The pair got into the tune, with Lopez smiling brightly to the lyrics, "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."

"Dear Ben … Happy Birthday. I love you!" the "I'm Real" singer captioned the heartwarming post.

Back in July, the cute couple celebrated Lopez's birthday at their new home. According to her On The JLO newsletter, Affleck threw Lopez a pool party in their new  $60 million mansion in the Wallingford Estates area of Beverly Hills.

Meanwhile, the pair are also about to celebrate the 1-year anniversary of their lavish wedding in Georgia on Aug. 20.

A source recently told ET that the couple are "doing well" as they are "acclimating to their day-to-day lives." 

"They have had a lot on their plates between their work, travels, moving, setting up their new home, and of course, taking care of their kids," the source shared. "They know that everyone has been getting used to the new adjustments and they want everyone to feel as comfortable as possible during the process. They are working on meshing their families in a healthy and gentle way, while also making sure everyone has a fun summer."
