London: British singer Tulisa Contostavlos has revealed in her autobiography that she was sexually assaulted after being drugged when she was 16.

The now 24-year-old recalled how she had seen her friends putting pills in people`s drinks and told them that she didn`t want to get involved on the night the alleged attack took place.

In the book titled "Honest: My Story So Far", which is being serialised by The Sun, Tulisa admits she even lied about having a heart condition in a bid to prevent her drink from getting spiked, reports dailymail.co.uk.

As the evening progressed, she recalls that all of a sudden she felt "abnormally drunk", despite only having a few drinks.

Following a few dizzy spells, the singer soon lost her footing and was escorted out of the club for fresh air.

Tulisa said: "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."

And worse still, on regaining consciousness, she found to her horror that her friend was having non-consensual sex with her, before she passed out again.

"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".
