Meanwhile, 30-year-old Danielle Instagrammed her own adorable throwback video of her and her hubby having some fun on the dance floor while dancing to Michael Jackson's "Rock With You." Jonas sports a black jacket emblazoned with "groom" on it, as he sweetly gives his gal kisses on the cheek.

"For 7 years this has been MY guy!" Danielle wrote. "He's an amazing friend, husband and dad. I love you more than words can say. #myguy #7years."

The couple married on Dec. 18, 2009 and have two kids together -- 2-year-old Alena, and their almost two-month-old daughter, Valentina, whom they welcomed in October.
