Want to give Demi Lovato a heart attack? Just ask her if she dated One Direction hottie Niall Horan.

No, but seriously, don’t.

Rumors of a romance between Demi and Niall have swirled off and on ever since, well, ever since Niall and the rest of 1D made it big in the US, really. Demi has been pretty good about laughing off the rumors – until now. In a recent interview with MTV, she cracked on the issue, admitting that she’s sick of hearing that rumor.

“I’m so tired of that! It never happened,” Demi said. “Niall’s a really sweet guy and I definitely consider him a friend, but it’s never crossed that line… He’s a sweet kid and we have an understanding, but we’re just friends.”

Well, there you have it. Sorry, Nemi shippers – looks like this one is a no-go.
