On Saturday (June 21), Morgan Wallen made an impressive entrance during the second night of his I’m the Problem Tour stop in Houston, walking out with rap superstar Drake and baseball legend Roger Clemens at NRG Stadium. This surprise walk out followed a similar moment during Wallen’s Friday show, where he was joined by NFL legend Andre Johnson and businessman Jim “Mattress Mack” McIngvale before his show at the home of the Houston Texans. Wallen shared the moment in an Instagram video, captioning his post, “all summer long.” The star-studded, pre-show walk out has become a signature of Wallen’s live shows, with previous guests including Travis Kelce, Tom Brady, Mike Tyson, and the Tennessee Volunteers baseball team. These shows kick-off Wallen’s 20-date I’m the Problem Tour, which is in support of the country superstar’s Billboard No. 1 album, which has ruled the chart for five weeks straight. The tour is set to hit 10 cities throughout the U.S., and will run through September 13. (Billboard)
