Taylor Swift says Ed Sheeran is obsessed with a sword that was used in the 'Lord of the Rings' trilogy.

The 23-year-old singer is currently on her 'Red Tour' with Ed, 22, and she has revealed his most prized possession is a sword that was given to him by Peter Jackson - who directed the fantasy films based on J. R. R. Tolkien's books.

Speaking to MTV News, she said: "He's got this sword ... he went to New Zealand and got this sword. The actual Peter Jackson gave him a sword from a 'Lord of the Rings' movie. And he was obsessed with it to the point where like he would come into by dressing room waving it and then just leave."

Ed even got the weapon out on a flight to Nashville which caused much concern amongst their entourage and the flight crew.

She explained: "He'd just get it out on the plane and everybody is like, 'We don't know if that's OK on a plane. It's a weapon, but it's a medieval weapon [so] we don't know.' "

Taylor - who duets with Ed on her latest single 'Everything Has Changed' - admits the 'Lego House' singer loves nerd culture and is always picking up film merchandise and geeky items.

She said: "He's obsessed with stuff like that. He's obsessed with Legos. He's obsessed with swords, like axes, stuff like that."
