The Ticketmaster list of shows matches the one "leaked" on Twitter on December 28.

Both lists include some impressive non-country names, including Cardi B on March 1 and Camela Cabello on March 5.

Country artists include Luke Bryan, Chris Stapleton, Kacey Musgraves and old favorites Brooks & Dunn, who are returning to the rodeo for the first time since they split up.

Tickets for Strait's show are not included in the RodeoHouston season packages and will be higher than normal rodeo prices. They were going for more than $300 on Ticketmaster before they stopping selling tickets Thursday morning.

A spokesperson for RodeoHouston said they don't know anything about the Ticketmaster sells, and AXS is their official ticket provider.

Tickets go on sale on Jan. 10.

It remains to be seen how ticket buyers will react to fewer country performances this year than usual.
