Breaking up is hard to do and especially when it happens in the spotlight. Just ask Taylor Swift's ex Calvin Harris. After a 15 month relationship Taylor moved on swiftly to a new romance with actor Tom Hiddleston, leaving Harris heartbroken. However, time heals all, or so they say, and that may be why Calvin Harris was seen on Saturday leaving a London nightclub with gorgeous former Pussycat Doll Nicole Scherzinger. However, sources close to Harris told TMZ he was simply offering Nicole and her friends a ride home and that he is still hurt from the break up with Taylor.
