After last night’s X Factor performances, rumors are swirling of a possible romance between Taylor Swift and One Direction star Harry Styles— and now show co-host Mario Lopez can confirm the pair were looking rather cozy together backstage.Tonight, on 104.3 MYFM's radio show On With Mario Lopez, the X Factor star goes into detail about what he caught the rumored pair doing behind-the-scenes.“During rehearsals, Harry from 1D came and slapped me on the back and said, ‘Hey Mario, how are you doing?’ I said, ‘What are you doin' here?’ He sorta points toward Taylor and I said, ‘Oh, good for you!’ Mario admits. “And then I see the two walking off hand in hand! So Taylor Swift and Harry from One Direction— you heard it here first — were officially hanging out!"We knew the pair were flirty, with several reports of Harry throwing Taylor over his shoulder and walking off with the “Red” crooner, but does their hand-holding mean there’s something more than harmless flirtation going on.Taylor seems to be moving on from ex-boyfriend Conor Kennedy fairly quickly, having only ending her relationship with the famous 18-year-old three weeks ago. If this isn't a song waiting to happen, we don't know what is.To get the full scoop on Taylor and Harry’s rendezvous, listen to On With Mario Lopez -- check onwithmario.com for air times.
