Justin Bieber kept mum on the subject of his split from girlfriend Selena Gomez, after a two year relationship in a recent interview, neither confirming nor denying the news of the breakup. The teen popstar was dodging breakup talk during the interview on November 10. “I don’t know what to say,” Us magazine quoted him as telling Open House Party radio host John Garabedian.“I don’t know what’s going on in my life . . . To even assess that it doesn’t make sense ‘cause I have not made any comment’,” he said. Gomez, meanwhile, has maintained a low profile since their Oct. 31 breakup, hopping a plane from LAX to New York Nov. 10 after wrapping production on her Disney series Wizards of Waverly Place.
