There's no bad blood between Harry Styles and Taylor Swift. The One Direction singer celebrated his 22nd birthday on Monday by tweeting a lyric from his ex-girlfriend's song 22 – much to the surprise of fans.

"I don't know about you, but I'm feeling 22," Harry tweeted to his 27.1 million fans.

The social media post attracted a mixed reaction from fans, with one exclaiming: "I've been waiting my entire life for this tweet."

Others created amusing memes related to Harry's tweet, photoshopping his face into Taylor's 22 music video.

Harry and Taylor dated for around three months at the end of 2012, and Taylor reportedly drew inspiration from their romance for her album 1989, most notably in single Out of the Woods.

Taylor touched upon the nature of their relationship as she introduced the song at the Grammy museum in 2015, admitting that she knew it was doomed from the start.

"I'm going to play you a song that I wrote about a relationship that I was in that the number one feeling I felt in the whole relationship was anxiety," Taylor said. "Because it felt very fragile, very tentative.

"And it always felt like, 'Okay, what's the next road block? What's the next thing that's gonna deter this? And how long do we have before this turns into just an awful mess and we break up? Is it a month? Is it three days?"

The pair have both since moved on, and while Taylor is happily loved up with boyfriend Calvin Harris, Harry has most recently been linked to another former flame Kendall Jenner after the pair holidayed together in St Barths over the New Year.

It is not known how Harry spent his special day. The Drag Me Down singer had started the celebrations two weeks early by joining friends including Nick Grimshaw for a birthday dinner in London in January.
