Harry Styles and Taylor Swift's puppy love affair is going strong, and it looks like her dad gives his blessing.

The happy couple was backstage at Z100's Jingle Ball concert where Taylor performed, when Taylor planted a kiss on Harry just before he did a little dance number with Scott Swift, the father of his girlfriend du jour.

Later, at an after party, 22-year-old Taylor and 18-year-old Harry recreated the famous "Dirty Dancing" moment whenPatrick Swayze lifts Jennifer Grey into the air. (Wait -- isn't that movie a little before Harry and Taylor's time?)

The backstage peck was caught on video then uploaded to YouTube, while the dance duet was photographed and posted to Twitter.
