Louis Tomlinson and Eleanor Calder were reunited when he got home from New Zealand

Louis Tomlinson is very upset with the Twitter trolls who have taunted girlfriend Eleanor Calder with pictures of him with his ex Hannah Walker.

They also got 'Louannah' trending on the site, which left the One Direction star distinctly unamused.

'Truth of the matter is its actually not funny in the slightest. I'm reading through some horrible tweets very pissed off!' Tweeted Louis, 20, earlier this week.

Louis, 20, then made sure part-time model Eleanor, 19 - who's studying politics and sociology at Manchester University - knew she's the only one for him.

'Love YOU ! xxxx,' Louis, who's now back from New Zealand, told his girl.

Eleanor replied: 'Love yoouuu xxx.'

But the campaign to get Louis back with his ex went viral, with the trolls telling Louis he should break up with Eleanor, 19, and go back to Hannah.

A primary school teaching assistant in Doncaster, Hannah now has 140,000 followers on Twitter.

Louis's spokesman tells the Mail Online: 'It's upsetting for Louis and Eleanor when Twitter campaigns like this start.

'I know some of the fans will think it's a bit of fun, but it's unnecessary when they are both very happy together.'
