One Direction star Louis Tomlinson's family name new hamster after his girlfriend Eleanor Calder

Eleanor Calder has clearly become close to boyfriend Louis Tomlinson's family.

The One Direction star's younger siblings Daisy and Phoebe have decided to name their latest pet after the 19-year-old student.

'@drdeakin How cute is our new little hamster? She was named 'Eleanor' by the twins @EleanorJCalder,' Tweets Louis's mother Jay, along with a photo of the animal.

Eleanor replied '@JayTommo @drdeakin Haha! Cute! Can't wait to meet her :) xxx.'

Mum Jay and Eleanor are both missing Louis, 20, while he's on 1D's first headline tour of the US - which ends this weekend.

But their time away from the singer has given them an opportunity to bond.

When a fan Tweeted: '@JayTommo it would be perfect if @EleanorJCalder was your daughter-in-law xx,' Jay replied: '@elounorph @EleanorJCalder Yes it would :) x.'
