Leona Lewis unveiled a new curvier figure at the Summertime Ball in London yesterday.

The former X Factor winner wowed fans at the event in an on trend black jumpsuit and matching pair of gladiator sandals.

Lewis took a break from recording her new album in Los Angeles in order to attend the event at the Emirates Stadium in North London.


Leona Lewis looks curvier than usual at Summertime Ball.

She sang a series of her hits for the crowd during what was a rare public appearance in the UK.

Despite winning the talent show in 2006, Lewis has rarely performed in the country and has yet to announce a full live tour.

Other performers at the event included Katy Perry, who wowed fans with such hits as 'I Kissed A Girl' and 'Hot N' Cold'.

Boy band Blue also reunited for the outdoor bash, while The Saturdays and Enrique Inglesias also performed.
