The Saturdays singer - who is now romancing soccer player Wayne Bridge following the demise of her two-year relationship with McFly bassist Dougie Poynter - says people come to her if they want an honest opinion on their situation, but she prefers to learn from her own mistakes.
She said: "All my friends say they come to me when they want to hear the truth. I will say it how it is.
"Personally, I like to learn my own lessons. And when people are like, `He`s a bad guy, he`s a player`, I don`t listen.
"Every player eventually meets someone who makes them stop f***ing around. Everyone deserves a chance."
Despite her views, Frankie loves catching up with her bandmates - Vanessa White, Rochelle Wiseman, Una Healy and Mollie King - and admits they discuss everything in their lives.
She told more! magazine: "We`re all so loud. Mollie is the loudest when we go out - and she doesn`t even drink.
"We talk about everything. Mainly just a load of crap.
"In the morning, you kind of think, `That made sense last night but it doesn`t now.` "
