Rocking a lineup stacked with country artists at a show in Wyoming this summer, somehow Post Malone makes sense.

The chart-topping crossover star was just announced as a performer at the Cheyenne Frontier Days show on 7/25, on a lineup that also includes Tim McGraw, Keith Urban, Miranda Lambert, Lady Antebellum, Rascal Flatts and more.

Cheyenne Frontier Days is a 10-day outdoor festival of entertainment and rodeo, that has been held annually since 1897 and draws close to 200,000 people each year.

It may seem unusual to include Post, but the Texas native is surprisingly comfortable in a rootsy musical environment. If you saw him rocking "Baby What You Want Me to Do" with Urban on the recent Elvis TV tribute, you know what we're talking about.
