Pink and Carey Hart Are Officially Our Favorite Couple This Valentine's Day -- See Their Super Sweet Posts!

Carey Hart is gushing over his wife, Pink, and we can't handle the cuteness.

The former freestyle motocross racer took to Instagram on Tuesday, sharing a series of pics and sweet messages dedicated to the mother of his two children, daughter Willow, 5, and son Jameson, 1 month.

One of the photos featured a vintage pic of Hart all dressed up in his signature Fox racing gear, sitting on his No. 46-plated dirt bike, seemingly shot prior to a competition. A cheery Pink, clad in a casual striped tank top and beige hat, was happily by his side.

"As I sit here on Valentines morning w/ a very fussy 7 week old, I'm very thankful for my Valentine of 15 years," Hart, 41, captioned it. "There is no other person on this planet that I'd rather be on this crazy ride with."

"Though we want to strangle each other at times, that's what keeps the passion alive lol," he joked. "I love you baby. Thanks for the gifts that are our children, your love, and support. And you have a really nice hiny ?. @pink."

One post simply wasn't enough, as Hart also shared a vintage snap of the two locking lips near his truck. "Yep, she is a badass woman," he exclaimed. "Love my valentine. @pink."

The 37-year-old "Just Like Fire" singer returned the love, marveling over her "sweet sweet valentine" on her own Instagram page.

"I've been loving you for so long I don't remember what it's like not to," she wrote.

It doesn't get much cuter than that!

Pink and Hart celebrated their 11th wedding anniversary in January. The two met at the 2001 X Games in Philadelphia, Pennsylvania, and in 2005, the pop star 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!" He quickly pulled off the track, letting his fellow racers pass him, and said "Yes!"

While they've had their fair share of ups and downs -- they briefly separated in February 2008 but got back together in April 2009 -- we're happy to see that their love is still going strong.
