Harry Styles Celebrates 22nd Birthday by Quoting Taylor Swift and Making a Big Solo Career Move

New year, new Harry Styles!

The One Direction member is celebrating his 22nd birthday on Monday with a series of bold moves. First: quoting his famous ex-girlfriend, Taylor Swift.

Oh, yes. Those are the undeniable lyrics of Swift's catchy-as-hell song, "22" -- which, to be fair, has been quoted by practically every single human who has turned 22 after Red's 2012 release.

As if that wasn't enough to get the Directioners buzzing, Styles also rang in his new year with a major business move -- and it could very well mark the beginning of a solo career.

Billboard reports that Styles has officially split from One Direction's longtime management team, Modest Management, signing with CAA music manager Jeffrey Azoff (son of industry power player Irving Azoff) in Los Angeles.

"We wish Harry the very best," Modest Management confirmed to Billboard in a statement. "It has been a real pleasure working with him... Harry is a total gentleman, and we know our good friend Jeffrey Azoff will look after him. We look forward to sharing some great wine with them next time we are in L.A."

But don't get #RIPOneDirection trending on Twitter just yet. A source reportedly told Billboard that "nothing has changed" regarding the hiatus plan for the band, and that "all will be revealed in due time from the band members' own mouths."

The move comes just a few days after Styles' former bandmate, Zayn Malik, launched his very first solo single, "Pillowtalk," and a steamy music video with Gigi Hadid.
