The Saturdays star has revealed why she checked into a clinic and had time out of the limelight.
Frankie has revealed that the reason for her recent absence was due to a medical condition, insisting "it wasn't rehab".
She told The Sun: "I was hospitalised, it wasn't rehab. I don't think there's anything wrong with rehab. It takes a lot of courage to enter facilities to try to beat any addiction or overcome issues, but mine is a medical condition"
"I will talk about it in detail one day soon, for the sake of my fans, as they want to know. But I will say it wasn't alcohol, drugs or an eating disorder. And the dark days are now behind me. My family, friends and boyfriend Wayne have been wonderful."
Meanwhile, Frankie along with bandmates Una, Rochelle, Mollie and Vanessa are gearing up for the start of their UK tour, which starts tomorrow (8th December) at the LG Arena in Birmingham.
