Mummy Bieber stands up for her son

UNITED STATES - It is mummy to the rescue.

Appearing on US talk show Watch What Happens: Live, Ms Pattie Mallette, 37, defended her son Justin Bieber's recent public indiscretions.

The 19-year-old Bieber's controversial acts included being two hours late for a performance, urinating into a mop bucket and yelling an expletive at a photo of former president Bill Clinton.

It was also reported on Thursday that Bieber was kicked out of a Chicago nightclub for underage drinking.

Ms Mallette said: "He knows what I disagree with, and he knows all the things that I'm really proud of him for... People don't talk about all the great things he does every day."
