NEW YORK: Justin Bieber has telephoned Bill Clinton to say sorry for cursing him and spraying his photo with cleaning fluid in a NY restaurant kitchen earlier this year. The ex-president’s office confirmed the pop star had apologised and offered to help the Clinton Foundation. Before exiting, the singer sprayed the Clinton photo and swore in reference to him. Bieber tweeted to his more than 41m followers, thanking Clinton “for taking the time to talk”. “Your words meant alot. #greatguy,” he tweeted. Bieber performed in a concert at Chicago’s United Centre on Tuesday evening before visiting the venue.–WO
