Taylor dating One D star?

Taylor Swift and Harry Styles have been spotted "holding hands", sparking rumours that they are dating.

X Factor host Mario Lopez was surprised to see the One Direction hunk on the set of the show this week, until Styles explained he was with the Begin Again singer, who was performing on the reality show.

Speaking on his 104.3 MY FM radio show, Lopez said: "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.

"[Later I saw them] walking off hand in hand. So Taylor Swift and Harry from One Direction – you heard it here first. [They’re] officially hanging out, I can say that much."

Meanwhile, a source close to Styles told Radar Online that the One Direction star isn’t ready to get serious.

A source close to Harry told gossip website RadarOnline.com: "Taylor and Harry have been quietly seeing each other again. When Taylor dates someone she jumps in full force, but Harry is being a little more cautious this time around.

"Taylor is a hopeless romantic, so she’s really hoping it works out with Harry. Harry’s being really sweet with her right now and careful not to hurt her. But at the same time, he’s a young, popular heartthrob who isn’t quite ready to be tied down."

The couple are said to have briefly dated in April but parted ways after she saw photos of him kissing American model Emma Ostilly in Australia.

The insider said: "Taylor really liked Harry and even though they weren’t exclusive, he hinted at making it official with her just before he took off to Australia… [one morning ] Taylor had all these texts from Harry begging for a chance to explain and telling her not to believe everything she read. 

"She immediately googled Harry and found all the stories and pictures of him kissing Emma. She was heartbroken."

And it seems that Styles (18)  is already getting on well with 22-year-old Swift’s family.

A source told E! Online: "Harry is there with her now. She is doing rehearsals this afternoon…He was sitting with her mom and the rest of her entourage.

"After she finished, he went up to the stage. They were joking and laughing. He picked her up and threw her over his shoulder and carried her off."

Swift has been single since her recent split from Conor Kennedy, while Styles has been linked to a string of women, including singer-and-actress Natalie Imbruglia and model Cara Delevingne.
