Tulisa reveals her 'shame and embarrassment' after being sexually abused in new book Honest: My Stor

Tulisa described how she was spiked during a horrifying night that saw her waking up in a 'strange house'

In a shocking extract from her new book, Tulisa said that she was sexually abused by someone who spiked her drink on a night

In a horrifying passage from Honest: My Story So Far - which is being serialised by The Sun - The X Factor judge claimed that her friends used to spike people's drinks on nights out, so she pretended to have a heart condition so they wouldn't do it to her.

But on a night out when she was 16, Tulisa described feeling "abnormally drunk" all of a sudden and was taken out of the club for some fresh air after a series of dizzy spells.

She then revealed: "The next thing I remembered was waking up lying in the back of a cab and seeing the street lights whizzing past me through the windows.

"I felt completely out of it, and I blacked out again."

When she came around, Tulisa was horrified to find herself in an unfamiliar bedroom with her 'friend' having non-consensual sex with her.

Unable to fight the man off, Tulisa recalled: "I couldn't even move, let alone get up or speak, and once again I just blacked out.

"When I finally woke up in the morning I found myself in a strange house."

After coming face to face with the boy's mum in the kitchen - who assumed Tulisa was her son's girlfriend and offered her a cup of tea - the N Dubz star said she felt "so embarrassed and ashamed" that she couldn't tell her.

Tulisa added: "I went into the bathroom and burst into tears.

"Then I pulled myself together, got dressed, and left without saying another word, crying all the way home."

And although Tulisa, 24, says she has now "come to terms" with the terrifying ordeal, she never reported the crime.

In a new interview with the Sunday Mirror, Tulisa's father Plato said he would "kill that person" if he found out who it was.
