Which other Hollywood romances were real and which were a publicity stunt?
Is Taylor Swift really dating One Direction's Harry Styles? Because sources say, she's faking it to make ex-boyfriend Conor Kennedy jealous.
A source told gossip website HollywoodLife.com: ''She isn't denying in any way the reports of the people talking about her having a relationship with Harry because she wants to make Conor jealous and the way she thinks she is making him jealous is to show him that she has options, but in reality, she actually wants Conor and is just doing this to 'Wear the pants in the situation!' She has no interest in making the Harry thing work.''
It's a little too early to tell, plus Taylor is a wee bit of a serial-dater. Anyway, she won't be the first one to fake a romance (Jennifer Aniston, we're totally looking at you!).
