Louis' half-sibling Georgia Austin is upset by the taunts

Louis Tomlinson‘s half-sister Georgia Austin has been getting bullied by One Direction 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.

She’s posted photos of herself cuddling up to both Louis and his band mate Zayn Malik, 20, on her Twitter page.
