Taylor Swift and Harry Styles are apparently an insufferable item now, and one One Direction fan who isn't taking the news very well is Hailie Scott Mathers, BKA Eminem's teenage daughter.

"[I]f @taylorswift13 is really dating the love of my life @Harry_Styles i will not be happy," the 16-year-old wrote on her Twitter feed (the real one).

She went on to offer the unlucky-in-love Swift some unsolicited dating advice: "Dear @taylorswift13, please stop whoring around with every guy you see. We all know you're only doing it so you can make another album."

To which Taylor Swift responded in the Twitter feed in her mind, "y u jelly tho."
