Robin Roberts & Partner Amber Laign Celebrate 15 Years Together

Robin Roberts and Amber Laign have reached a milestone in their relationship.

Sunday on Instagram, the “Good Morning America” co-host regrammed a post from Laign that celebrates the couple's 15-year anniversary.

In her loving post, Laign posted a photo collage — comprising 15 pics for the 15 years they've been together — that Roberts had printed on a canvas. At the center reads, “Stand by Me,” the name of Laign's favorite song.

In her note, Laign remembers her first date with Roberts — which almost never happened!

“15 years ago, I met you for drinks on a blind date that both you and I tried to cancel...twice. Your grace caught my eye right away and the ease of the evening continued to flow through dinner,” Laign wrote. “We had a second date soon after and I couldn't believe how at ease I was with you as we shared each other's lives sipping lychee and apple martinis.”

When Roberts left for Tahiti the following day, Laign began feeling “butterflies” in her stomach.

“During that time apart, I grew this feeling inside of me that still, is very present today....butterflies. Having you by my side is a gift as we continue to navigate this thing called life. I drive you crazy....I know which is why I love you even more to this day,” she wrote.

Overall, Laign says Roberts has “the kindest heart and most beautiful soul than anyone I know.”

“You have shown me time and time again to stay humble and to always treat others with the utmost respect as you never know what one might be going through,” Laign continued. “Beautiful.....absolutely beautiful. I love you with all my heart.....boo boo.”

“Happy 15th Anniversary!!” Laign concluded.

Last December, the two enjoyed a trip to the Maldives, which required the couple to take a scenic yet scary flight on a seaplane.

“14 hour flight from JFK to Dubai...then 4 hour flight to Male...then this sea plane to our holiday destination. Totally worth it! (Sweet Amber squealed a little when the buzzer sounded on landing!)” Roberts wrote at the time.
