Former X Factor contestant Stephanie Nala got Twitter users in a twist after using the microblogging site to ask what Ebola was.

The 20-year-old from Cheryl Fernandez-Versini's Girls category - who was eliminated after coming bottom of the public vote on Sunday's Live Results Show - tweeted in all sincerity: "What is Ebola?"

She swiftly deleted the post after being labelled "ignorant" by fellow users, with others questioning how she could be unaware of the current crisis sweeping across the globe.

Nala then added: "Lol I've learnt to google things before tweeting."

The reality TV star, who reached the final of Britain's Got Talent with the now-defunct band Luminites last year, had previously been saved following Deadlock during the first Live Show.

Cheryl also lost contestant Chloe Jasmine on Sunday, and spoke of her disappointment onXtra Factor to host Sarah-Jane Crawford.

On Nala, she added: "She's very distinctive. It's one of those finding tunes... and with the themes you have to be very, very careful with Steph because her voice is so distinctive.

"On a record you would automatically know it's her but on stage with the themes it kind of hindered her a little bit. That's what I think happened
