"Happy anniversary to my MUCH better half," he captioned the black-and-white photo, which also features their 4-year-old daughter, Willow. "10 years is a pretty amazing milestone for 2 misfits like us. I'm proud of us baby!!! Thank you for being an amazing wife, mother, and friend. I love you."
Hart, 40, and Pink (whose real name is Alecia Moore), 36, said "I do" in 2006. The two met at the 2001 X Games in Philadelphia, Pennsylvania, and in 2005, the "So What" singer adorably proposed to Hart on a race track in Mammoth Lakes, California. As Hart was coming up on his third lap during the Pro 250 class finals , Pink held up a pit board that read, "Will You Marry Me?" followed by "Serious!" Needless to say, he quickly pulled off the track, letting his fellow racers pass him, and said "Yes!"
While they've had their ups and downs -- they briefly separated in February 2008 but got back together after attending marriage counseling in April 2009 -- we're happy to see that their love is still going strong a decade later.
