Kevin Jonas and Danielle Jonas celebrated seven years of marriage on Monday.

The 29-year-old singer and 30-year-old mom-of-two marked the occasion by dedicating sweet posts to each other on Instagram.

"7 years happy anniversary my love @daniellejonas 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," Kevin captioned a photo of himself with Danielle at their wedding.

"For 7 years this has been MY guy! He's an amazing friend husband and dad. I love you more than words can say. #myguy #7years," Danielle added to a video on her own account.

Kevin and Danielle tied the knot at Oheka Castle in Huntington, N.Y., in 2009 after two years of dating. The couple welcomed their first child, daughter Alena, in 2014, and their second daughter, Valentina, in October.

"We are so excited to welcome our new baby girl, Valentina Angelina Jonas to the world today. She is healthy and beautiful and we couldn't be happier," the pair said in a statement to People at the time.

"Alena already can't wait for Valentina to come home and start being a big sister," they added.

Danielle had delighted fans in November by sharing a first photo featuring both of her daughters. Kevin had said on SiriusXM's Nigel Barker's Gentleman's Code prior to Valentina's birth that he was hoping for another girl.

"I've always just wanted two kids that were both girls, and my wife was like, 'Why?' I'm like, 'Because I've been around boys so much my entire life, that I want to be surrounded by girls," he explained.

Kevin and his brothers Joe and Nick Jonas came to fame as the pop group the Jonas Brothers. Joe has since formed the band DNCE, while Nick has pursued a solo career.
