Eminem, Foo Fighters, Muse and Coldplay will headline the 2011 edition of Lollapalooza, to be held in Chicago on Aug. 5-7.

Eminem receives top billing on the lineup, which was unveiled at midnight this morning. The rapper will be busy on the summer festival circuit, as he's also among the headliners for June's Bonnaroo fest in Tennessee.

Foo Fighters will be supporting their latest album, 'Wasting Light,' and its lead single, 'Rope,' which topped the Rock and Alternative charts. Muse just won a Grammy for Best Rock Album for 'The Resistance,' while Coldplay haven't released an album in three years but are said to be finishing up their fifth studio recording.

The rest of the Lollapalooza lineup is heavy on indie rock bands and electronic acts, including My Morning Jacket, Girl Talk, Sleigh Bells, Bright Eyes and '80s rockers the Cars, who are about to release their first album in 24 years.

Among the pop and hip-hop artists featured are Christina Perri, Skylar Grey, Kid Cudi, Tinie Tempah and former Fall Out Boy frontman Patrick Stump.

Also worth watching is Cee Lo Green. Hopefully he'll be given a better time slot than at Coachella, where he showed up late in protest and had a meltdown on stage.

Lollapalooza takes place in Grant Park in Chicago. Earlybird tickets have already sold out. Regular tickets remain available at $215 for a three-day pass. The full lineup is available on the Lolla website.
