Big Sean joined Usher for a surprise love fest on Thursday night (Sept. 12) during the first of the Usher: Past Present Future Tour shows at Little Caesars Arena in the rapper’s home town of Detroit.

Usher brought out Big Sean two-thirds of the way into the concert, during “Superstar” — which the latter samples on “Who You Are (Superstar),” a track from his just-released sixth studio album Better Me Than You.

“If we’re gonna come to Detroit we gotta make sure to shout out all the legends,” Usher told the crowd before introducing Big Sean, who spit out some lines from his track followed by his 2015 single “Blessings” as he and Usher waded into the crowd to walk to a second stage at the rear of the arena floor, which was decked out like a strip club, complete with a pole dancer and a bar.

“Big Sean, I don’t mind you taking over the stage, but I gotta make a drink,” Usher said as he got behind the bar, mixing drinks for VIP fans in the area. Big Sean then took over with a rapid-fire mini-set that included portions of “So Good,” “A$$,” “Bounce” Back” and “I Don’t Fuck With You.”

He also told the crowd that Usher had accompanied him to the downtown Detroit Boys and Girls Club earlier in the day to inspect the facility, including its recording studio. Thanking Usher for allowing him to sample “Superstar,” he noted that “me and Usher haven’t done a song together. We made a promise we’re gonna do a song together,” although he did not say when, and even if, that might happen.”

Big Sean did get in a plug for Better Me Than You before heading off and leaving the rest of the show to Usher — who will be back at Little Caesars Arena on Friday, Sept. 13.

It was the latest major performance for Big Sean in his home town this year. He performed on the opening night of the National Football League draft in April and was part of the nationally televised opening concert for the newly renovated Michigan Central, the city’s former railway station, in June. He was performing earlier Thursday evening for a private show at a nearby nightclub, and on Monday, Sept. 16, he’ll be performing “a very special acoustic you” sponsored by Amazon Music at the Detroit Institute of Arts.

Usher — who performed the halftime show at Super Bowl LVIII in Las Vegas on Feb. 11 — kicked of the Past Present Future tour on Aug. 20 in Washington, D.C. and wrap up the North American leg with rescheduled concerts in his home town of Atlanta during December. A European tour begins March 29 in London with the first of 10 dates at the O2 Arena, as well as performances in Paris, Amsterdam and Berlin.
