Singer Selena Gomez was spotted here flaunting a more curvaceous chest than ever before, sparking rumours that she may have gone under the knife for some re-sculpting.

She was roaming around freely at a sidewalk here sans a brassiere, and her enhanced bosom was more than noticeable, reports dailystar.co.uk.

However, so far no comment from Gomez's representative has confirmed that she's gone under the knife.

Gomez wore ripped jeans, a chic blazer and clingy tank top for the outing, and she looked different from what she looked in March.

Her fans took to Twitter to share views on her latest look and several of them felt "the 21-year-old has fallen victim to the pressures of boosting her cup size".

One social networker posted, "Yeahhhhh selena gomez must've had a b**b job", while another added: "Selena Gomez totally got a b**b job. No ones b**bs are that naturally perky with no bra."

A third fan posted: "Pretty sure Selena Gomez got a b**b job lol they were NOT Like that."
