ROYAL Variety Performance viewers were shocked by Ellie Goulding's appearance, claiming they didn't recognise her.
Many fans took to social media during the ITV1 broadcast of the annual extravaganza.
The Love Me Like You Do singer, 35, took to the stage to perform a rendition of the Eva Cassidy classic, Fields of Gold.
And while her goosebump-inducing version got a thumbs up from viewers, they couldn't believe how different the star looked.
"Is that Ellie Goulding?! WTF has she done to her lips?!?!!!#horrified" one wrote on twitter.
A second added: "Nah, that’s never Ellie Goulding."

And a third chipped in: "Wow Ellie Goulding’s had a bit of work done hasn’t she?"
But despite thinking the singer has undergone quite the transformation - her usual blonde locks were dyed brunette too - they praised her vocals.
"Stunning" and "class" were just two of the adjectives thrown around on the social media platform.
Ellie is a mum to 17 month-old baby son Arthur, who she recently revealed could follow in her musical footsteps.

Asked whether he has shown any signs he is musically gifted, Ellie said: “Yes, which I’m very proud of. He can do scales, he’s only 15 months but he’s very singy. He is very musical and loves classical music. He’s got some musical genes, I’m very happy about that.”
And Arthur will have somewhere to hone that talent as he grows up, as his pop star mum is making a music hub at their home in Gloucestershire.
Ellie, who has three No1 singles and four hit albums, explained: “I’m building a music studio. I had a little shed and I’ve put all the stuff into it. It’s kind of already there.
“It’s so I can spend more time with my son and still work, otherwise I’m leaving him. I want to hang out with him all the time."
