Why Harry Styles tweeted Taylor Swift lyrics

Harry Styles celebrated his 22nd birthday with a surprising tweet.

Harry Styles celebrated his 22nd birthday by tweeting Taylor Swift lyrics.

The One Direction star's short-lived romance with the 26-year-old musician is believed to have inspired a number of her songs and to mark his birthday on Monday, Harry took to his Twitter account to tweet a line from Taylor's 22 from her Red album.

I don't know about you, but I'm feeling 22.

— Harry Styles. (@Harry_Styles) February 1, 2016

Meanwhile, it has been claimed that Harry's rekindled romance with Kendall Jenner, 20, is on the rocks.

The couple have apparently been enjoying a long-distance romance after they vacationed together in St Barts over the New Year, but it has now been revealed that Harry isn't keen on settling down with the model.

A source shared: "They are still going to carry on as friends. Harry doesn't want to settle down so he would never get a serious girlfriend during this phase of his life... in Harry's eyes it was never anything official."

The pair had a brief fling in 2013, enjoying a string of dates before calling things off but had remained friends before their recent reconciliation.

The insider added to The Sun on Sunday newspaper: "Harry and Kendall have got back together before but, in her eyes, it's very much off at the moment and he's arguing it was never even really on."
