One Direction star Louis Tomlinson has become involved in a feud with BBC Radio 1 DJ Nick Grimshaw.

The spat started when the singer tweeted that he couldn't leave his Australian hotel room due to the paparazzi, calling them "tw*ts".

Grimshaw, a close friend of Tomlinson's bandmate Harry Styles, then talked about the tweet on his breakfast show, saying: "I love a complainy popstar. It's my favourite thing.

"All complainy. 'I can't go outside because I'm famous'. Mask. I'm gonna wear a [Radio 1 producer Matt] Fincham mask. If you're gonna go outside, Psy mask."

Tomlinson's girlfriend Eleanor Calder was first to defend the 21-year-old. When a fan tweeted that they had "never liked Grimmy", she replied: "Me neither!"

Tomlinson himself then got involved, tweeting Grimshaw directly to suggest that his Radio 1 predecessor Chris Moyles was a better DJ.

Grimshaw appeared to refer to the incident this morning, tweeting:

I don't even like Nick much but he dragged here
