Ferne and Charlie were believed to have called time on their romance in December, shortly after reuniting at the end of series 10, but now the reality star says they haven't ended things for good.
"I can't confirm that we've definitely split," Ferne exclusively tells Reveal. "There's been so much speculation. We're still in contact but we have been more off than on.
"We've always had an up and down relationship, so I think you'll definitely see a lot of that in the new series," she added.
Ferne, who will be back on screens this Sunday for the new series, isn't worried about new cast member Grace Andrews, who is apparently set to stir up some drama in the show. "She's no threat to me," Ferne tells us. "He [Charlie] wouldn't date her, he's still in love with me."
Speaking of new cast member Grace, Ferne continued: "I don't know of her personally but I was filming with her the other day. I know of her from the area and we know someone who she used to go out with."
Hairdresser Ferne had been dating Charlie for three years before she made her debut on TOWIE in June last year. But the couple split in the summer after Charlie was accused of being unfaithful while on a lads' holiday abroad.
Despite it turning bitter at first, viewers saw the couple reunite in November when Charlie declared his undying love for Ferne as he begged for a second chance.
TOWIE series 11 airs Sunday 23 February 2014 at 10pm on ITV2.
