Father-to-be Kanye West has hinted he will be a no-show at the 2013 Grammy Awards, despite receiving six nominations for music's biggest night.

The "Stronger" hitmaker, who announced on Sunday he and his girlfriend Kim Kardashian are expecting their first child, will compete in categories including Best Rap Performance and Best Rap Song, but he's upset after missing out on nods in the main award sections.

West voiced his Grammys frustration onstage at a gig in Atlantic City, New Jersey on Saturday and suggested a possible boycott of the upcoming prizegiving.

He ranted, "How many Grammys do we have? 18 Grammys. All in the black categories, though, but nonetheless, 18. I love Maroon 5, but when I lost Best New Artist to Maroon 5... you know what I mean? Or when Watch the Throne and (My Beautiful) Dark (Twisted) Fantasy, neither of them got nominated for Album of the Year, you know what I mean? Or when N**gas in Paris didn't get nominated for Record of the Year, you know what I mean? So don't expect to see me at the Grammys this year, you know what I mean?"

West is tied with leading acts fun., The Black Keys' Dan Auerbach, Jay-Z, Frank Ocean and Mumford & Sons, who also have six nominations each.
