Posing in a cropped top and baring her midriff, Ella revealed her super slimmed-down body following a strict post-X Factor diet.
The 17-year-old has embarked on a healthy eating scheme this year in a bid to shed the pounds for her album release.
And by the looks of these snaps, it's certainly paying off.
Revealing her diet secrets, Ella got on board the 'tweet what you eat' trend, uploading several pictures of her meals over the past week.
And from super healthy salads with grilled chicken and vegetables to muesli with banana, she's certainly taking things seriously.
Ella first showed off her new figure last week, posing in her bathroom mirror for a bikini selfie on Twitter.
The singer previously expressed her lack of desire to shed the pounds just for her career, insisting that being thin didn't make her happy.
Revealing that she was underweight at 15, Ella said she's more concerned with finding the right balance.
She said: "I’ll never be a size zero, that’s just not going to happen but I’m simply going to be myself and I hope people will accept me for who I am."
Ella spent some time at a 'detox' bootcamp earlier this year to start her slim down, before heading out to LA to record her debut album with Sony.
