"Yum yum yum yum yum yum yum yum yum yum yum ? that's one for every year care bear. I really like you this week. #happyanniversarymylove I'm very lucky to be able to say that you're mine. Thanks for sticking around ?," she captioned a snap of the two locking lips.
Hart and Pink tied the knot in 2006, after meeting at the 2001 X Games in Philadelphia, Pennsylvania. In 2005, the singer adorably proposed to her former freestyle motocross racer beau on a racetrack in Mammoth Lakes, California, holding up a sign reading "Will You Marry Me?" during his third lap during the Pro 250 class final.
The two briefly separated in February 2008, but got back together in April 2009 after marriage counseling, and welcomed daughter Willow Sage in 2011, and son Jameson Moon just a few weeks ago on Dec. 26.
