Looking tasty in the Big Apple! Jesy Nelson quickly goes from drab to fab as she swaps baggy travel attire for ab-baring bralet hours after NYC arrival

She has enjoyed quite the eventful week, after opening up the BRIT Awards with her Little Mix bandmates and later returning to the stage to accept their first ever gong.

And on Friday - two days after the glittering ceremony - Jesy Nelson was spotted sporting a triumphant smile as she jetted over to New York City from London.

Apparently excited by her arrival in the Big Apple, she quickly swapped her baggy bomber jacket and leggings for a sexy bralet with ripped skinny jeans as she showed off her rippling abs in a selfie she posed to Instagram.

Earlier in the day, Jesy and her bandmates Perrie Edwards, Jade Thirlwall and Leigh-Anne Pinnock were given a roaring reception as they touched down at JFK airport, where they were met with balloons and congratulatory signs from fans.

The Touch singers kept a low profile as they made their way through the bustling terminal, especially Perrie, who covered up in a faux-fur trimmed coat.

The blonde beauty captioned the snap, 'What a night!, adding a love heart.

But it was her hand on stomach pose which really caught the eye of fans, many of whom descended into meltdown after falsely assuming the picture was designed to announce her pregnancy.

One fan enthused, 'Congrats!!!! Can't wait for the baby @perrieedwards !!!!!', while another posted, 'Are you pregnant?', and a third enthused, 'Y is she holding her stomach like that. What's going on'.

Perrie was also enjoying something of a personal victory with the win being over her ex-beau Zayn Malik, who was nominated for his track Pillowtalk.  

The duo's relationship has gone from strength to strength, with them recently going 'Instagram official' two weeks ago with a sweet photograph of themselves kissing in Paris

Perrie's latest string of videos even saw her completely merge her features with Alex's with a sweet line using their initials saying: 'AxP'

The duo are thought to have been dating since last November, but they are reportedly keen to avoid being defined by their romance.

Aside from her stream of hits from X Factor-formed girlband Little Mix, Perrie is still best known across the pond for her engagement to ex-One Direction star Zayn Malik.

He called off the engagement in August 2015, almost four years after they were first linked, and is now dating US supermodel Gigi Hadid.
