Grammy-winning artist Alicia Keys is set to join Usher as a featured guest in his highly-anticipated Super Bowl Halftime Show. Sources have confirmed that Keys rehearsed with Usher on Thursday inside Allegiant Stadium, solidifying her appearance as the first confirmed guest. Fans are speculating that the duo will perform their 2004 hit duet "My Boo," a song that topped the Billboard Hot 100 for 6 weeks and became a staple at high school dances worldwide. Usher, known for his numerous collaborations, negotiated a 15-minute set for the performance, allowing him to showcase his extensive repertoire of hits.

In addition to Keys, fans are also expecting appearances from Ludacris and Lil Jon, Usher's "Yeah!" collaborators, who were prominently featured in his Apple Music commercial promoting the event. There have also been rumors of Usher potentially bringing Justin Bieber on stage, but nothing has been confirmed. With all eyes on Usher this Sunday, the addition of Alicia Keys will surely elevate the show to even greater heights.
