Lollapalooza 2011 Lineup: Muse, Foo Fighters and Eminem Reportedly Headlining

Foo Fighters, Muse and Eminem are among the headliners for the 2011 Lollapalooza festival, according to the Chicago Tribune.

The names of three other headliners for the August festival have yet to be released. The official lineup and schedule won't be announced until April, and no acts have been officially confirmed. A handful of other groups have already been rumored, however, including Crystal Castles, Girl Talk, Lykke Li and Best Coast.

The Tribune is so far the sole source on the rumors, though their music reporter Greg Kot is annually one of the first in the know when it comes to all things Lollapalooza.

The announcement is just the latest big tour news for the Foo Fighters, who will release their first record in four years this April. They were recently announced as headliners for Washington's Sasquatch! Festival in May, and will play a series of festival gigs in Europe in June before heading back to the states for Lollapalooza.

And for Eminem, it's getting hard to imagine how much sweeter the angry rapper's current life can get. He starred in a pair of ads during the Super Bowl last Sunday, and is up for 10 Grammys this year.
