Chicago MC Chance the Rapper has recently been touring Europe with Eminem, but he won't be joining Em on his next tour, as many expected.

Chance took to Twitter over the weekend to apologize to his fans and to tell them that exhaustion -- or "being mad tired" -- is the reason for him not going. A poster was leaked late last month that promoted the tour, which was dubbed the "Rapture 2014." On it, Chance was billed as an opener, along with Kendrick Lamar, J. Cole and Action Bronson. A new version has since been released without Chance's name (Kendrick, J. Cole and Bronson are still expected to perform).

 

The tour, which starts early next year, will make three stops in Australia and one in New Zealand. No word yet if the tour will eventually make its way over to the states.
