The 17-year-old, who won The X Factor last weekend, recently confirmed she is seeing someone – which allegedly came as a shock to her ex-boyfriend, Ellis Stevens.
According to The Sun, Ellis was in a relationship with Louisa during the early stages of the ITV competition, but they broke up so she could concentrate on the show.
He’s said to have told the publication: “We split up because she wants to follow her dream. It was only recent, like in the last couple of months. I didn’t want to get in the way of her career and what she wants to do.
“We had been going out for about 18 months and I know her manager and family really well.”
Louisa recently confirmed she is taken – and the lucky man is thought to be 19-year-old Essex boy Daniel Elliott.
Addressing her confession, Ellis allegedly added: “I saw what she said about that and was shocked. I went to some X Factor shows and supported her early on but don’t know what’s going on now.”
Despite this, Ellis is said to have taken to Facebook last night to insist he has not sold a story.
He wrote: “I think in total I have been offered around 30,000-40,000 for stories and pictures but it still won’t make me say anything because I’m not that type of person to be messing with mine and others lives [sic].”
