Pink and Carey Hart Celebrate 18th Wedding Anniversary: 'Proud We Made It to the Other Side This Year'

The couple, who first met at the 2001 Summer X Games, married in 2006 and have since welcomed two children together

Pink and her husband Carey Hart are celebrating 18 years of marriage!

In honor of the occasion, the former professional motorcyclist, 48, posted a touching tribute to the "All Out of Fight" singer, 44, on Sunday, reflecting on all of the life adventures they've packed into their more than two decades as a couple.

"In the last 18 years of marriage to this amazing human, we have done so much together. Raise two amazing children, travel the world, go on adventures, love, argue, make up, support each other, laugh, cry, laugh more, breakup, get back together, party, mourn, grow, and a million other things," he wrote on Instagram.

"There is no one else on this planet I’d rather do it with than you. 22 years in each other [sic] lives and I’m looking forward to the next 22," he continued, jokingly adding, "As long as you don’t kill me first 🤣🤣🤣🤣. Love you baby!!!!! Happy anniversary, @pink."

Hart's anniversary post featured several candid photos of the pair, including a shot of them sitting next to each other on a swimming platform at a lake.

Another photo was a blast from the past, capturing them both sporting wildly different hairstyles back in the early days of their relationship — Hart a spiky mohawk and Pink a shaggy pixie cut with neon pink accents.

Later on Sunday, the Grammy winner also honored the occasion with a lengthier tribute. Like her husband, the pop star shared a handful of nostalgic shots on on Instagram, including some of the two cozying up to one another in the early days of their relationship, a photo from their wedding and several more recent, romantic images.

In the caption, the singer-songwriter opened up about the highlights of their marriage and how it hasn't been without struggles. "Love is a lifetime of coming back to the table," Pink began.

She then revealed how challenging their relationship has been, even within the past year. "We almost didn’t make it to this one, well a couple of them, if I’m being honest," she continued.

"When I met you, 22 years ago, I just wanted someone that wouldn’t lie to me. I didn’t have a clue about commitment, building a life together, intimacy, trust. It’s f---ing hard," the star wrote. "But man if I’m not humbled by the surprise of loyalty, history, forgiveness, and resilience. How love rearranges itself and reappears after an empty night or five."

"I’m proud we made it to the other side of this year. I wear our scars proudly. You are my stubborn, beautiful, immovable rock," the Trustfall artist reflected.

Pink concluded her tribute by sweetly summing up how much she values her relationship with Hart. "The family we’ve built and the stories we have weaved together and the memories we continue to make are worth more than a thousand million awards that anyone could give me. I love you and I love us. #18years #improudofyou #family," Pink wrote.

Pink and Hart, who share daughter Willow, 12, and son Jameson, 7, first met at the 2001 Summer X Games, which turned out to be an eventful day for Hart in more ways than one. Not only did he encounter his future wife but he also shattered his right foot, and broke three ribs and his tailbone while attempting a mid-air flip on his bike.

The pair hit it off and began dating, but their relationship had some rocky moments early on. They briefly broke up in 2003 and then reunited a year later. After Hart proposed at one of his races in June 2005, they tied the knot in January 2006 in a beachside ceremony at the Four Seasons resort in Costa Rica.

However, just two years later in August 2008, they announced they had separated, only to reconcile and call off their divorce in May 2009. Since then, they have been going strong.

In 2021, as the couple celebrated their 15th wedding anniversary, Pink told PEOPLE one of the secrets to their marriage was that they had evolved and "grown up together" while carving out their own identities as individuals.

"When you first get together, you look at that person as your entire world. One person can't be your entire world. You have to have your own passions, your own friends, your own time to yourself," Pink explained at the time. "I used to be super needy. Now we expect less of each other, and that allows us to give each other more somehow."

On Hart's 48th birthday in June 2023, Pink reflected on her husband's personal evolution over the "21 birthdays" that they had celebrated together. "I’ve watched you grow from a young, gorgeous, insane athlete into a wise, even more gorgeous businessman, entrepreneur, father and husband," she wrote in an Instagram post.

She added, "You are just getting started and I’ve loved growing up with you and raising little humans together."
