Yep, Olly Murs has been taking the mick out of Taylor Swift's songwriting abilities. OLLY MURS.

The 24-year-old singer has branded his comments "sexist" after the former X Factor star essentially mocked her for writing songs about her ex-boyfriend Harry Styles (and so on).

Speaking on Australian radio station 2DayFM, she said: "You're going to have people that are going to see the depth from which you approached a song - that you put your real emotions into it and that that's valuable and that's good and that's real. And then you're going to have people who are going to say, 'Oh you know she just writes songs about her ex boyfriends.' But I think frankly that's a very sexist angle to take. No one says that about Ed Sheeran. No one says that about Bruno Mars. [They're] writing songs about their exes, their current girlfriends, their love life and no one raises a red flag there. The most important thing to me is about maintaining artist integrity."

Olly called out Taylor on the same radio station last week shortly after her latest song Out of the Woods - which is said to be about Harry (they dated for three months until they split in January 2013, for fear you had forgotten) - was released.

He said: "Come on [Taylor], let it go. Write something new that isn't about Harry. Bless him, it's been like two years and he's still getting lashed out of it isn't he?"

Olly also poked fun at the rather successful singer - who has sold 30 million albums, don'tcha know - by singing Out of the Woods (badly). For the record, the song is about a death-defying snow mobile accident Taylor had with an ex-boyfriend, and how he 'cried' after getting a number of stitches in his chin.

They are never EVER getting back together.
