Big Brother contestant Ellis Hillon has been removed from the reality TV show following an investigation into offensive social media posts she made before entering the house.

It comes one day after the 19-year-old Scottish fast food worker entered the house during the live launch of what will be the last series of Big Brother to air on Channel 5.

Hillon reportedly wrote a message about the September 11 tragedy on Twitter in 2014 which contained a racist slur.

Other users shared the tweet that was uploaded four years ago.

It allegedly said: “Oh f**k its 9/11!!

“RIP to everyone who died n f**k they smelly p**i terrorist b******s”

Ellis’ account has since been deleted from social media.

A spokesman for the programme said: "As a result of our investigation into offensive and unacceptable posts on social media, Ellis Hillon has been removed from the Big Brother house."
