One Direction star Louis Tomlinson's sister bullied by fans who don't believe they're related

Some Directioners think Georgia, 14, is lying about having a famous sibling because she and Louis have different surnames.
Some of the harsh comments the teen's received include: 'He doesn't love you', 'Who do you think you are?' and 'He's not your brother'.
Georgia is the daughter of Louis' biological dad Troy Austin, who split from his mum Johannah Poulston when the 1D star was a child.
Johannah, 40, gave Louis, 21, his stepfather Mark Tomlinson's last name - although the couple divorced in 2011.
She's now engaged to new love Dan Deakin.
Louis last saw his dad around three years ago when he let him know about his success on The X Factor.
Troy, 44, says the Doncaster-born singer has met Georgia three times, including once during a local radio event several years ago and another time at his hotel.
Georgia is a huge One Direction fan and had the 'time of her life' when Troy took her to see the group perform live in Nottingham earlier this year.
