Tulisa’s shock at mum-in-law’s tell-all book

TROUBLED X Factor star Tulisa Contostavlos has been dealt another blow – her stepmum is writing a tell-all book about her.

Tulisa, 24, who was left shattered two weeks ago when a sex tape of her and ex-boyfriend Justin Edwards came out, has been betrayed again by step-mum Melanie Vondrau.

She’s set to lift the lid on Tulisa’s selfharming and involvement in gang culture in a book called Phoenix Rising, due out later this year.

Melanie, 39, who was married to Tulisa’s dad Plato, 52, for 10 years before their divorce in 2009, is said to be appalled by her sex tape and this is why she’s turned on her.

A friend of the N-dubz babe said: “Tulisa is astonished Melanie is doing this. It’s disgusting for her to cash in on her misery.”

Tulisa admitted in a BBC3 programme Tulisa: My Mum and Me that she self-harmed for two years as she struggled to cope with her mum Ann’s mental illness as a teenager.

She said: “I’ve selfharmed. I want to help, but it stresses me out.”
