Taylor Swift has endorsed her friend Ed Sheeran after he made Time magazine's 100 Most Influential People list for 2017.
The prestigious list includes names like Donald Trump, Pope Francis, Kim Jong-Un and Riz Ahmed, who featured as the cover star for the magazine.
Fellow pop star and long-time friend Taylor Swift wrote a tribute accompanying Sheeran's entry.
"As a young, precocious redheaded boy growing up in Framlingham, Suffolk, Ed Sheeran decided he wanted to be a musician," she wrote.
"He started writing songs and playing instruments like so many hopefuls do, but something very different happened that would set in motion one of the most impressive self-made careers in music.
"Whether by choice or an unconscious evolution, when he decided on his musical ambitions, Ed became less of a boy and more of a tank.
"He is protected by an impenetrable and ever-present armour of enthusiasm that has helped him endure any setback, letdown or underestimation.
"His reaction to any idea that fails is to almost immediately come up with a new one. He's like a fighter who pops back up on his feet before you even noticed he'd been knocked down."
Tay-Tay also told of the time when Ed felt insecure and she gave him strength.
"A few years ago, in a rare moment of admitting feeling defeated, Ed said to me: I'm never going to win a Grammy," she wrote.
"Yes, you are, I said. You're going to sweep the whole thing one of these years.
"It was a few weeks later when he met me in a dance shoe store in London, where I was picking out rehearsal outfits, and said: You have to hear this.
"It was a song he'd just finished called Thinking Out Loud, which went on to win Song of the Year at the Grammy Awards in 2016."
Actor and TV personality James Corden was another high-profile Brit who made the top 100.
Sir Elton John wrote: "James is one of the most hardworking and talented people you will ever meet.
"His authenticity has allowed him to shape pop culture in an incredible way."
