They've only just reportedly started dating, but witnesses who saw Harry Styles and Taylor Swift together, backstage at X Factor USA last week reckon it's love between the popstar dream couple with the pair “lighting up” on seeing one another.
The One Direction hunk was first linked to Taylor earlier this year, but it appears love didn't blossom until her summer romance with Conor Kennedy went sour a few weeks ago and despite their busy schedules keeping them apart, the couple are said to be smitten.
"They lit up when they saw each other," an eye-witness told Us Weekly.
Referring to Swift, they went on: "[She] was a puppy dog."
While neither of the pair have confirmed the romance, X Factor USA presenter Mario Lopez confirmed the 'Live While We're Young' star was definitely there with the Red singer.
He revealed on his 104.3 MY FM radio show in the US: "Taylor Swift was the special guest performer, and [here's] a little inside scoop for you,"
"During rehearsals, Harry from One Direction came and slapped me on the back, and said, 'Hey, Mario, how ya doing?' And I said, 'What are you doing here?' And he sort of [pointed] toward Taylor."
He then added the couple, "walked off hand in hand.”
"So Taylor Swift and Harry from One Direction -- you heard it here first," he proudly announced. [They're] officially hanging out, I can say that much."
But how do the busy stars stay in touch? According to sources "they email a lot!"
They've yet to confirm the romance but, it looks like these two are enjoying "hanging out"!
