We have all kinds of developments in your favorite pop star pairings, friends and monitors of young love. First, Justin Bieber and Selena Gomez’s potential reconciliation seems to be off — they met at a Japanese restaurant in L.A. on Friday; they argued and Selena left a few minutes after arriving; Bieber drove to her house and was locked out; Bieber tweeted, “things arent always easy. there is alot of pressure. im figuring it all out. im trying. but i care, i notice, i still hear u. #Beliebers” (Phew.) Next, Taylor Swift and One Direction’s Harry Styles may still have a valid romance, despite Vulture’s scientifically arrived-upon theory that her new song “I Knew You Were Trouble” is about the young Brit — Styles swung by The X Factor to watch Swift tape a performance, and they left “hand in hand.” Love torn asunder, love rekindled!
