Veteran rappers Eminem and OutKast will headline the 13th annual Austin City Limits Festival in Texas this October.

Earlier in the week, the Detroit spitfire teased fans on Instagram regarding his appearance at the ACL music fest. "Square Dance with Me," he wrote next to an image of a cowboy on a horse with his face photoshopped on the image’s head.

Meanwhile, it looks like OutKast’s reunion tour will stretch into the fall. The duo gave a triumphant performance during the second weekend of Coachella after a disappointing inaugural show at the festival.

Much like Coachella, the ACL music festival will take place over two weekends -- Oct. 3-5 and Oct. 10-12 -- at Zilker Park.

Also on the bill are Childish Gambino, Iggy Azalea, Lorde, Skrillex, Lana Del Ray and Jimmy Cliff, among others.
