The former ‘Xtra Factor’ presenter had been dating music manager Jack for over a year, though it’s now believed that they’ve decided to go their separate ways.
A source tells The Sun: “She [Caroline] is absolutely devastated about her and Jack splitting up.
“It came to a natural end and was a mutual decision that they both agreed was for the best. No one else is involved on either side.
“Jack has been away so much because he’s very successful and Caroline is so busy with work.
“But she’s still very close to Jack — there isn’t some nasty fallout or dark secret.”
Caroline has impressed the judges during this year’s series of ‘Strictly’, and over the weekend she secured her place in the semifinals, topping the leaderboard.
According to show sources, Caroline’s break-up actually took place ahead of the shows.
“She was obviously completely ecstatic about getting through because she’s so passionate about the show,” an insider tells the paper. “But backstage she was distraught because she’s been privately struggling to keep it together over the end of the relationship.
“Caroline tried so hard to make it work but that’s pretty tough when you’re having to spend 12 hours every day rehearsing your routines.”
Caroline isn’t the first celeb to fall victim to the ‘Strictly’ curse, and in recent years the likes of Susanna Reid and Rachel Riley have both ended relationships during, or shortly after, their time on the show.
Rachel - who is now dating Caroline’s partner Pasha - has previously addressed her break-up, insisting that the romance did not develop during rehearsals.
"‘Strictly’ was something I really enjoyed doing, but it wasn’t the cause of anything,” she stated. “On ‘Strictly’, you form a close bond with your partner, but there was nothing romantic when Pasha and I were dancing. It was just dancing.”
