Just what is going on with Odd Future's Earl Sweatshirt? The rapper canceled on last weekend's Bonnaroo festival [article id="1709020"]citing pneumonia[/article]
 and on Thursday Delaware's Firefly Music Festival announced that Earl would be a no-show at their event as well.

His place will be taken by Schoolboy Q, but the second cancellation in two weeks has fans asking what's up with OF's most enigmatic member?

When reached for comment on Friday (June 21), a rep for Earl directed MTV News to his Twitter page, which read in part, "The worst part of pneumonia is that it won't f---ing go away. It's like dubstep," Earl wrote in al l caps on Tuesday, seemingly confirming that he's still suffering from the bacterial lung infection.

He hasn't given many details since about what is ailing him (and requests for comment from his spokespeople were not returned at press time), but last weekend he complained, "My mom's coming over and bringing me dinner cause my f---ing friend suck. F--- you guys."

Earl isn't the only one who can't make it to Firefly. The Lumineers also had to pull out due to an illness in the band. "We were all extremely excited to be a part of this great event and share our music with you," they wrote in a message to fans. "But the health and well-being of the band along with giving the fans the best possible performance remain our top priority."

There are plenty of other bands to check out at Firefly, though, including the Red Hot Chili Peppers, Vampire Weekend, Calvin Harris, MGMT, Kendrick Lamar, Azealia Banks, Zedd and the Alabama Shakes.
