Jerry O'Connell and Rebecca Romijn celebrated their 15 years of marriage by sharing sweet tributes for each other.

The 48-year-old actor shared a photo on his Instagram page Thursday to mark the special occasion. It features him and Romijn, enjoying in a pool of water. There were massive rocks in the background as the couple posed together for a selfie.

"15 Years Today!" O'Connell wrote. "This one puts up with my Mommy Issues, cheapness and is infinitely out of my league. INFINITELY. HAPPY ANNIVERSARY! Love ya, Babe!"

The 49-year-old actress also took to Instagram the same day to share a series of photos. In the first photo, the couple can be seen sitting in a restaurant/cafe wearing matching outfits and sunglasses.

The next photo shows the couple walking hand-in-hand somewhere in Italy. In the last photo, they seem to be posing together on the Spanish Steps in Rome.

"Still smiling after all these years," she wrote. "Happy 15th Anniversary @mrjerryoc Love you!!"

Romijn also shared a photo featuring the couple in what appeared to be Turkish outfits and wrote, "Wonderful Istanbul Anniversary with my Sultan. @goturkiye you are breathtaking."

Ahead of their wedding anniversary celebration, O'Connell had shared thoughts on spending over a decade with Romijn.

"We haven't thought really about it because I think we're both shocked that we made it this far," O'Connell told ETOnline last month. "We're still getting over just the shock of still being married."

O'Connell and Romijn tied the knot in 2007. The couple shares 13-year-old twin daughters - Dolly Rebecca Rose and Charlie Tamara Tulip. Romijn was previously married to actor John Stamos. The actor is now married to Caitlin McHugh.

Romijn spoke about her first marriage when she appeared on "The Talk" in May, ETonline reported. She shared that she does "have a lot of really fun memories" of her ex-husband.

"A lot of things about him that I miss," she added. "But yeah, it's tricky. It's a very hard decision to come to when you decide to end a marriage. It was heartbreaking."

Mystique’s scaly blue skin required Romjin to wear a custom bodysuit with more than 100 prosthetic pieces that covered over 60 percent of her body. The full effect took nine hours to apply.She couldn’t fly, use skin cream or even drink wine the day before shooting because it could alter her body chemistry and cause the prosthetics to fall off.
