Pattie Mallette, the mother of Canadian superstar Justin Bieber, has hit out at the GRAMMYs for not nominating her son in any of this year's categories.

Despite having an incredibly successful year, Bieber hasn't been nominated for any titles at the 2013 GRAMMYs and Mallette explained that she's not only really disappointed, but surprised at the organisation for not recognising his talent:

"I think they blew it. It's my boy, I'm a little biased. I just heard that he's had now five No.1 albums, so I think his music is speaking for itself."

When asked how the 'As Long As You Love Me' hitmaker had taken the news, she admitted that it's giving him something to work towards for the next ceremony: "I think it's kind of good in a way. It gives him something to strive for and a goal to go for."

The 2013 GRAMMYs will take place this coming Sunday on February 10 in Los Angeles.
