The singer left a camera crew astonished with his comments when they approached him on a night out in Los Angeles.

Williams told reporters that he had been “w**king and shooting heroin” when asked about his recent activities upon leaving an LA hotel.

“Yeah, w***ing. Shooting heroin. What else have I been doing? Just being malicious. Bum sex,” the Daily Snack quoted Williams, as telling the reporters.

The 33-year-old’s comments were aired on US telly show TMZ before 7pm, with added subtitles to help viewers understand his accent.

However, his friends insisted that Williams, who relocated to LA five years ago, was just joking around and hopes viewers were not too offended.

“Robbie was just having a laugh. Hopefully Americans get his sense of humour and won’t take any of the stuff he said seriously,” a friend said.

“He probably wasn’t expecting the footage to be used on TV, especially at such an early hour and with subtitles. They seemed to find it hilarious on TMZ and everyone was laughing along,” the friend added. (ANI)
