She certainly is WILD! Jessie J performs at the Summertime Ball in an entirely see-through dress... before raising eyebrows with her very sexy dance moves

It might have been a family show, but Jessie J appeared determined to raise eyebrows as she performed at the Capital FM Summertime Ball on Sunday.
The 25-year-old singer took to the stage wearing an entirely see-through black net dress as she belted out her hit songs at Wembley Stadium.
Jessie then caused further controversy by performing some incredibly provocative dance moves as she was joined for the performance by B.o.B.

Rocking out: Jessie drew attention to her toned figure in the outfit, under which she wore nude underwear

The singer bumped and ground with her co-star, who appeared honoured by her attention, as the duo performed to the 80,000-strong crowd.
Jessie teamed her net dress, under which she wore a triangle bra and high-waisted underwear, with a pair of leopard-print plimsolls, so her footwear didn't get in the way of her moves.
Earlier, Jessie had admitted on Twitter that she wasn't feeling 100%, but added that she wasn't going to let her illnss stop her from giving the performance her all.

She wrote: 'Time to rest before glam time! I refuse to be sick! No no no sickness! You ain't gonna win! Muhahahaha!'
And the WILD singer certainly didn't give in to her illness as she belted out tracks including Price Tag and Lazerlight.
Jessie also worked her shaved head for the performance, wearing a pair of gold hoop earrings to further draw attention to her buzz cut - which she had done to raise money for Comic Relief.

What's going on? But his thrusting later proved a bit too much for the 25-year-old singer

Speaking recently about the decision to have her head shaved live on television, Jessie said it was one of the produest moments of her career.
She explained: 'Shaving my head was a massive highlight. I've been wanting to do it for a long time but I wanted to be famous enough that it would raise a lot of money.'
And referring to other career highlights, Jessie said: 'The Olympics last August were unreal, it feels like yesterday and it was the most exhilarating feeling to be part of Britain's history. The Queen's Diamond Jubilee, obviously, was a huge moment, too.'
Prior to performing at the Summertime Ball, Jessie wore a skintight white dress and jacket as she posed up backstage with Robbie Williams and Marvin Humes.
