Mum is number one for Justin Bieber at his new film premiere

Proving he’s only got eyes for one woman, Justin Bieber turned up for the New York premiere of his new film Never Say Never with his mother Pattie on his arm.

In fact, the crowd of teenage fans that usually follow the star around were replaced by a select group of 'grown-up' celebrities.

The low-key ceremony on Wednesday night was a stark contrast to the day before in Toronto where streets around the cinema came to a standstill for the 16-year-old’s fans.

Thousands of die-hard Bieber-lovers – dubbed ‘Beliebers’ – had camped overnight to catch a glimpse of the star and even threatened riots when they were denied cinema entry.

The teen sensation’s new movie – released in the UK on February 18 – follows him on his 2010 concert tour and features appearances from stars such as Usher, Miley Cyrus, Sean Kingston and Jaden Smith.
