We could use some good news around here. Just a day after the Writers Guild decision not to picket the 2008 Grammy Awards comes word that next month’s CBS telecast will feature a Tina Turner-Beyoncé duet. In a word? Genius.

There’s no question Beyoncé can hold her own with Tina — unlike Cher, who caterwauls her way into this 1970’s variety show duet with Turner and sounds occasionally out of breath trying to keep up:

But what’s Cher got to do with it? The question at this point is: what will Tina & Beyoncé sing? Imagine Miss Tina schooling the hip-pop princesson “Nutbush City Limits” or “River Deep, Mountain High.” (As long asB’s “Check on It” is left out of it, I’ll be happy.) PopWatchers, are you as crazy in love with this news as I am? What do think we’ll hear from the two divas Feb. 10?
