N-Dubz star, now a judge on The X Factor, has published extracts from her forthcoming autobiography Honest in The Sun newspaper.
She writes: "I had too many boys too soon. I regret losing my innocence so early.

"I can still count on my fingers and toes the number of guys I've slept with. A good percentage of those encounters happened between the ages of 14 and 17 and that felt like a lot, even at the time.
"Despite my street-girl persona, I was totally into the idea of fairytale romance. I wore my heart on my sleeve and I was ready to give my all if I thought I was going to get love in return.
"Of course, it wasn’t the right way to go about things, because any attention and affection I got from those men was usually only temporary, but it took me a while to learn that lesson."
