Alicia Keys will be a featured guest at Usher's Super Bowl Halftime Show she rehearsed with Usher inside Allegiant Stadium she'll be in the mix the first confirmed guest of his BTW all signs pointing to them doing one big song together we're talking about their 2004 mega duet "My Boo" which will undoubtedly be at least one of the tracks she performs. Usher negotiated to have a 15-minute set as opposed to the originally allotted 13 minutes 'cause it's the only way he knows how to rock, it seems. Considering how many famous collaborators Usher has had over the years it makes sense he needs the extra time. His Apple Music Commercial to promote the big event also heavily featured his "Yeah!" collaborators Ludacris and Lil Jon. Most everyone assumes these two guys will also be special guests during his performance although, they technically haven't confirmed yet.
