Kendrick Lamar and SZA have been sharing the spotlight with each other on their current Grand National Tour, and the “All the Stars” collaborators are bringing their A-list friends into the fold during select shows.
Playboi Carti was the first guest performer, popping out for “Good Credit” at the Atlanta show in April after Dot had been performing the MUSIC track solo since the tour’s opening night in Minneapolis on April 19. Both Baby Keem and Kaytranada came out as surprise guests, performing “Family Ties” and Teedra Moses’ “Be Your Girl,” respectively, during the concert at the “Kill Bill” singer’s home state of New Jersey earlier in May. While SZA performed her “Consideration” collaboration with Rihanna from the latter’s iconic 2016 album Anti at the Jersey stop, fans could only hope and dream that RiRi would one day join her on stage.
The stars have also been spotted on the sidelines, as videos of Pusha T attending their Foxborough show went viral.
After AzChike performed during the DJ Hed & Friends portion of The Pop Out: Ken & Friends concert on Juneteenth last year, he became the first featured rapper on GNX to pop out as a guest during the trio of shows in Lamar’s hometown of Los Angeles in May, when they performed “Peekaboo” together. Meanwhile, SZA brought out Lizzo and Justin Bieber during the other two LA nights to perform the remixes of “Special” and “Snooze,” respectively.
Billboard rounded up all the guest stars who’ve popped up at the Grand National Tour, in order of oldest to most recent appearance.
