Singer Justin Bieber has reportedly put a beep on ex-girlfriend Selena Gomez's name that appears in his upcoming song. Sung by Nicki Minaj, Bieber's new song Beauty and a beat had Gomez's name in one of the lines.The lyrics were - "Justin Bieber, you know I'm a hit 'em with the ether, buns out, wiener, but I gotta keep an eye out for Selena.""It's too late for Justin to remove the lyrics from his album. But there's no way he's going to be singing it or have anyone else sing it - including Nicki - at his concerts," thesun.co.uk quoted a source as saying. "He knows it would just rub salt in the wounds for Selena and there would be a huge backlash from his girl fans, so it's easier forgotten," the source added.According to reports, Gomez and Bieber ended their two-year-old relationship last week over trust issues.
