That's one way to promote your book! Tulisa shows off her cleavage in all its glory as she leans forward during autobiography signing

It was only a couple of days ago that she attempted to go for the butter wouldn't melt look in an angelic white dress to one of her book signings.

And on Thursday morning she even looked classy as she showed up to record a number of radio interviews across London dressed in jeans and a cream knitted jumper.

But on Thursday night Tulisa Contostavlos caused quite a stir as she reverted back to her skimpy dresses - and gave quite the eyeful as her curves were well and truly on display.

The N-Dubz star was in Milton Keynes this time to promote her tome, Honest: My Story So Far.

And she dressed to the nines, clearly in the mood for a girlie number as she wore a black and white frock with studded detailing on the strapless top with a sweetheart neckline.

On first sight it was only Tulisa's legs that were on full display as she finished off her look with strappy black shoes and her bleach blonde locks worn down in tumbling waves.

That's better! She opted for a black and white frock with stud detailing and managed to keep her curves intact when she first showed up for some photos

Taking her seat: The X Factor judge seemed unaware quite how much flesh she was displaying as she adjusted herself on the seat

But when she sat down to take her seat, ready to sign her books for the waiting fans, Tulisa gave them more than they bargained for as she pulled herself forward, thus leaning down to reveal her cleavage.

The X Factor judge seemed unaware she was showing off quite as much flesh as she was as she prepared herself for the lengthy meet and greet session.

Once she was perfectly in place, Contostavlos still showed off her curves as she sat down for the event, but not quite as much as when she first readjusted herself in the chair.

Pen at the ready: She sat ready to scribble her autograph and chat to her fans who were patiently waiting to get their hands on a copy of the tome

It was only a few hours earlier that she stunned for a different reason - for actually covering up in a classier number of jeans and a jumper for her promotional schedule.

On Thursday morning the singer turned up to record an interview on BBC Radio 1 in London.

She completed her look with a cream knitted jumper with studded detailing on the shoulders.
