The 26-year-old looked stunning at the Cosmo Awards last night, hitting the red carpet in a corsetted Dolce and Gabbana gown.
But Ellie's frock looked SO amazing that already there are rumours circulating that she may have gone under the knife to enhance her bust.
The singer looks a world away from the snaps of her taken in a bikini in 2011, which coincided with her quotes surrounding plastic surgery.
Ellie admitted that her obsession with running and working out had led her to slim down in all the wrong places.
At the time, she told 3am: "Sometimes I feel I would like a boob job because I have run my boobs off."
"When you run as far and as often as I do, the boobs are the first thing to go. But I don’t think I would ever get it done, because I like running too much."
The star's latest bikini snaps, taken just four weeks ago, show her revealing her alleged new cleavage while she was on holiday with pals.
Just this month Ellie told Cosmo that she's much happier with her body after becoming more confident about her looks.
She told the magazine: "I went through a time of being quite insecure. I’d convinced myself I was fat; I didn’t like my figure and I had a big nose.
"Now I’ve finally got to a place where I don’t focus on those things. I feel like I’m not changing for anyone; I’m doing it all for myself because there’s no-one else to do it for."
But it's not the first time fans have questioned whether Ellie has had some work done.
Last year a fan tweeted Ellie to ask her whether she had had a boob job after spotting a busty snap on Ellie's Instagram page, to which she never responded.
Omg! have contacted Ellie's spokesperson for comment.
