Troubled musician Kanye West leads the Grammy Award nominations with 7, but the bad boy producer was a no-show at last night’s live concert warmup to the 2012 Grammy’s in February.

While Kanye’s hit all-star single, “All of the Lights,” was nominated for Song of the Year, his critically acclaimed album, My Beautiful Dark Twisted Fantasy, which featured ‘Lights’, was snubbed in the Best Album category.

But Bon Iver, who was a complete stranger to many of us before collaborating with Kanye on MBDTF, was nominated for 4 Grammy’s, including Song of the Year — which Kanye is also nominated for — and Record of the Year, which we assume is different from Song of the Year.

Fading rapper-turned-actor LL Cool J, 43, (pictured above) attended the concert after party with his long-suffering buxom wife, Simone Smith. I bet she has a lot of stories to tell, such as why LL Cool J is bleaching his skin when he’s already a light alabaster color. Or why he still calls himself “Ladies Love” Cool J, when they don’t.

Singer Melanie Fiona is too nice, which is why the blogs virtually ignore her.

Remember when we used to LOVE Taraji P. Henson, back in the day before she flipped the script on us?
