Taylor Swift and Harry Styles 'officially' datingAdd to Favorites | The X Factor
"The X Factor" co-host shared the "inside scoop" about the "Red" singer's guest performance Thursday:
"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."
But wait, there's more!
The British boy-bander and six-time Grammy winner "walked off hand in hand," says eyewitness Lopez.
Swifty's last romance, with Conor Kennedy, 18, ended in October after a whirlwind summer romance.
But apparently she's moved on to another 18-year-old. (Or moved back -- according to several tabloids, Swift and Styles had a spring fling before One Direction toured Australia in April.)
"So Taylor Swift and Harry from One Direction -- you heard it here first," concluded Lopez. "[They're] officially hanging out, I can say that much."
