Kevin Jonas Posts Sweet 7th Anniversary Message to Wife Danielle -- See the Romantic Pic!

Kevin Jonas is celebrating seven years of wedded bliss.
On Monday, the 29-year-old singer took to Instagram to wish his wife, Danielle, a happy anniversary. Kevin shared a cute snap of the two slow dancing, and called Danielle an "amazing wife and mother."
"7 years happy anniversary my love @daniellejonas," he wrote. "So blessed to have you in my life. An amazing wife love and mother! You are the best, I love you with all my heart."

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. 
Kevin proudly shared the first photo of Valentina later that month. "Say hello to my newest love Valentina," he Instagrammed.
