Justin Bieber has apologised by phone to Bill Clinton for cursing the former president and spraying his photo with cleaning fluid in a New York City restaurant kitchen earlier this year.
Mr Clinton's office said the pop star called and "he apologised and offered to help the Clinton Foundation." Mr Clinton's office declined to provide any other details.
A video released on Wednesday by TMZ.com showed the 19-year-old urinating in a mop bucket as he and others race through the restaurant kitchen. Before exiting, Justin sprayed the Clinton photo and swore in reference to the former president.
Justin tweeted to his more than 41 million followers on Wednesday night, thanking Mr Clinton "for taking the time to talk." Justin tweeted: "Your words meant alot. #greatguy."
