Demi Lovato - Demi Lovato And Niall Horan: Is She Dating The One Direction Singer?

Demi Lovato and Niall Horan enjoyed a cosy dinner together after the MTV Video Music Awards. But are they dating? 20 year-old Demi and Niall - who turns 19 this week - went to Morton's Pink Taco Century City for Mexican food, after the high-profile awards ceremony last week. A source told E! News that the young couple looked as though they were enjoying an "intimate date" as they shared their appetizers at the restaurant. It's certainly fuelled rumours that they may be dating, even if Demi has denied the suggestion in the past.

Earlier in the summer, Demi was quick to play down the rumors that the two of them were forging a romantic liaison, saying "No, I'm not [with him]. He's really sweet and he's one of my really good friends now. But I'm single at the moment. And I plan to be for a long time because I need to focus on my career and myself and my well-being before I think about getting in a relationship with anyone." Niall has been slightly less coy about his feelings for the X Factor judge and Camp Rock actress, though. The One Direction singer told Access Hollywood just last week that he has a crush on Lovato.

As if that wasn't enough, they've also been spotted tweeting each other, now that they are in separate countries. On Sunday night (September 9, 2012), after Niall said that he wanted to catch up with the X Factor episodes that he'd missed, Demi relied by saying ".@NiallOfficial Yep...things are about to get very interesting!!! #Sept 12." At least - we think she was still talking about X Factor!
