SO unfair, right?!
Joining Nick Grimshaw on his radio breakfast show, Ellie showed no signs of tired eyes as she stepped out looking flawless in her stylish getup.
Teaming ripped jeans with a sheer black blouse, the 28-year-old injected a little sass into her outfit with a gorgeous pair of leopard print boots.
Not just on point in the style stakes, Ellie was a champ on the beauty front too, sporting perfectly tousled locks, fluttery lashes and a cute bubblegum pink gloss on her lips.
Telling Nick she had gone the whole night through without a wink of shut eye, Ellie credited her glam team for her flawless appearance in the early hours.
When told she looked amazing, the starlet said: "I have an incredible make-up artist."
"I'm so tired," she admitted. "I just didn't [sleep]!"
Meanwhile, promoting her new song 'Love Me Like You Do' featured on the soundtrack for the Fifty Shades Of Grey movie, Ellie revealed her new track was made exclusively for the upcoming film.
Ellie - who is dating McBusted's Dougie Poynter - explained film producers had showed her a scene from the movie, asking her to write a track to go along with it.
Without giving too much away, she did let on the scene in question wasn't that raunchy.
Last week, Ellie unveiled the video to 'Love Me Like You Do' featuring unseen bits from the movie.
Speaking about her music vid, she said: "I got to dance which was cool, I don't usually because I'm terrible at dancing. I had some lessons though, and it turned out alright!"
Like us, Ellie admitted she too can't wait for Fifty Shades to hit the cinema: "I'll definitely watch it. I think it's going to be amazing!"

In the movie, Christian is played by Jamie Dornan while Dakota Johnson takes the role of Ana. Rita Ora also stars as Christian's sister Mia.
