Haylor, aka One Direction hunk Harry Styles and Taylor Swift, are going at a breakneck speed. There have been trips to Utah to ski and to the Caribbean to relax in the sun, and that public New Year's Eve smooch. Clearly, the 1D heartthrob and the 'I Knew You Were Trouble' singer are in love and don't care who knows. But one person with a watchful eye on this romance, besides the hordes of Directioners that spew hate at T. Swizzle simply by virtue of jealousy, is her dad, Scotty Kingsley Swift.

Papa Swift, a stock broker who also guides his daughter's career, likes his little girl's latest BF. He doesn't think Styles is 'Trouble.' But he does want them to slow down a bit. It's moving at too rapid of a clip for his taste.

A source told The Sun, "He likes Harry but he wants them to slow down and take things easy. It’s clear to everyone they are smitten with one another and already talking about marriage. "

While the marriage talk may be a rumor that's spun out of control, Papa Swizzle is just looking out since he doesn't want his daughter left with her heart smashed to smithereens. Although, as a businessman, that'd be a good thing, since when Tay Tay gets her heart broken, she writes smash hits about it, as it's her therapy. He's clearly looking out for her as a dad and not as a manager.

“He doesn’t want them to split up as fast as they’ve got together and for Taylor to end up devastated," the insider said.

We don't want that, either! We're pulling for Haylor to work for the long run. She deserves some happiness! Plus, it seems like Hazza has the most noble of intentions. He reportedly gifted her with a vintage bracelet to show his love.

Wait, what's that sound. Oh, that's us, lying on the cold, hard ground, to borrow a phrase from Swift's latest single. Styles knocked us off our feet with his romantic gesture.
