Macklmore announced via Twitter today that Sir-Mix-A-Lot will fill the previously unannounced “Special Guest” opening slot at tomorrow’s installment in his three night sold-out run at Key Arena. Talib Kweli and Big KRIT will also be opening starting with tonight’s Arena show.

The announcement comes months after Mix-A-Lot was spotted towing Macklemore’s Cadillac. Apparently the two have resolved their autmotive dispute and are on good terms now, having reportedly bonded over their shared love of big butts.

No word yet on whether or not Sir Mix-A-Lot will be performing his most recent holiday single—Washington State Lottery jam “Fa La La La Lottery.”

“Mega-Millions/I’m actin’ a fool/I buy a mountain/Build a house/With a Seahawks shaped pool.”
