Ellie Goulding has sent out a heartfelt public apology to Niall Horan, but it's not for the reason gossip-watchers might think.

No, the 'Burn' singer wasn't referencing the epic rumored relationship triangle involving her, the One Direction heartthrob and Ed Sheeran. She was sorry for her cover of 1D's 'What Makes You Beautiful'!

Goulding, in an appearance on England's Capital FM radio show, was forced to sing the guys' signature smash while playing a game of karaoke. After confidently knocking out snippets of tracks by Jennifer Lopez and Katy Perry, Ellie was clearly delighted to then be assigned the 1D tune. "I love this song so much," she exclaimed while waving her hands in the air. "It's just a great song."

Did she sing it well? (Find out for yourself by watching here.) But if she didn't, she sent out an apology to "good friend" Niall. "If I did it badly, he'd definitely have something to say about it," she said. "Sorry, Niall."

Ellie and Niall's reported summer 2013 hook-up has been blamed by some for the bitter end to her short-lived romance with Sheeran.
