Singer Leona Lewis looked just swell as she arrived at a studio in New York for the recording of show Good Morning America.

In fact, the X Factor winner was showing off a decidedly bustier look as she took to the stage for the popular breakfast show.

It's not clear whether the look is temporary or permanent, but there were no complaints from the audience as the modest star took to the stage, wearing a tight white vest and lilac tube skirt.

Leona looks a shadow of her former flat-chested self, compared to an appearance at an awards show in London last summer

Leona was performing on Good Morning America as part of their Summer Concert Series.

Earlier, she hit the shops of New York for a shopping spree after it emerged that an album she recorded before winning X Factor is to be released. 

A source said: 'Leona made it before she was famous and didn't expect it to come back to haunt her like this.'

But the star and a pal didn't let it stop them shopping until they dropped, and they were all smiles as they struggled to carry their shopping bags packed full of booty.
