Interestingly, Grammy producers replaced original opening act Janet Jackson with Prince, who'll perform with Beyoncé.

Prince, as you may recall, sent Tipper Gore into a frenzy with his 1984 ode to masturbation, "Darling Nikki," and used to fill his stage shows with scantily clad, writhing female dancers. In 1991, he famously attended the Video Music Awards in skin-tight yellow pants, with panels cut out to reveal his butt.

But he's toned down his act since becoming a Jehovah's Witness a few years ago (interestingly, Jackson was also raised in the faith). Prince has even been reported to go proselytizing door-to-door in his native Minnesota.

"This may not be the Prince we knew from before," notes Blender editor in chief Andy Pemberton, who adds that he's nevertheless "thrilled" to see His Purple Majesty back in action.
