Horan cheers on Swift at O2 gig
Niall Horan appears to be getting friendly with his One Direction bandmate Harry Styles' ex-girlfriend, Taylor Swift.
The Irish singer was spotted at one of Taylor's O2 concerts and according to the Daily Mirror even got an access all areas pass and enjoyed drinks with her before the show.
Niall has been romantically linked to Hungarian Victoria's Secret model Barbara Palvin, but things have apparently cooled now that she has relocated from London to Paris.
Meanwhile, Harry, 20 - who is rumoured to be dating Kim Kardashian's little sister Kendall Jenner - has been celebrating his birthday in California.
Taylor, 24, is thought to have written her song I Knew You Were Trouble about Harry after they split on a Caribbean break in January 2013, following just two months together.
She apparently went back to her hotel after the O2 show on Sunday with her band to watch the Super Bowl and while Niall, 20, didn't mention having been at her concert, he later tweeted: "Watching the Super Bowl! And all I can think of is! 'I can't believe we are playing that stadium in the summer' mind blowing".
