Taylor Swift teams with Diet Coke

Taylor Swift has teamed up with Diet Coke.

The 'I Knew you Were Trouble' singer has partnered with the drinks brand for her 'Red Tour' in the US, and has promised a number of special tie-ins.

Speaking in a video posted on her website, she said: ''I wanted to share some news with you because we're actually making it official with one of the great loves of my life ... Diet Coke.

''We've been in conversations about this partnership that's gonna include so many fun things having to do with the tour, having to do with Diet Coke in general, behind the scenes of the commercial shoot.''

Taylor's ex-boyfriend, Harry Styles, has a deal with rival cola brand Pepsi, through his band One Direction. Taylor narrowly avoided a run in with the singer - who she split from over new year after two months of dating - at the NRJ awards, which took place in France over the weekend. She reportedly went out of her way to avoid any run in on the red carpet by delaying her arrival to the event by 25 minutes.

A said: ''It was very carefully timed so they didn't do the carpet at the same time.

''Taylor didn't do any backstage interviews and didn't use a dressing room - she changed at the hotel because she didn't want to see Harry at any point. Things were timed to keep them apart and for it to not become a big media circus.''

Taylor's Red tour kicks off in Nebraska, US, on March 13.
