Taylor Swift posted an endearing message for Ed Sheeran's 25th birthday.

The American pop star shared a story about meeting up with the ginger Grammy winner in a ballet shop in England.

"Looking back on the highlights of my life, there's a moment I'll never forget from a day in London about two years ago," Taylor wrote. "My friend Ed Sheeran met up with me in this little shop where I was buying ballet shoes."

"He walks in and says 'you have to hear this new song. I think it's the best one I've ever written.'" Ed then handed her a pair of headphones. "I sat there on a bench in that store and heard 'Thinking Out Loud' for the first time, as little kids were picking out tutus and leotards next to us. Little did we know it would go on to be first dance song at countless weddings all over the world, become Ed's biggest hit, and eventually go on to win him Song of the Year at the 2016 Grammys."
