However, when we caught up with Cazza at the InStyle Best of British Talent Pre-BAFTA party last night (January 30), the 32-year old insisted she is still very much single.
Speaking of her alleged romance with The X Factor 2013 champ, Caroline stated: "We just go out for drinks. I expected that, if I ever go out with a guy, they like to make up some sort of story.
"I think it's because my life is so boring and if nothing else is really going on, you have to create some sort of soap opera. I'm not going out with James Arthur. [My life] is probably more boring that you think."
While on the subject of love, Mollie King - who is the only single member of The Saturdays - was quick to dismiss any potential link to Flack's ex-boyfriend Harry Styles.
When asked if - like the rest of the female population - she fancies Hazza, Mollie stated: "We know him so well, he's like a little brother. We know all of One Direction very well so I will leave everyone else to Harry."
