Kanye West and Stevie Wonder will headline the 2011 edition of the Austin City Limits Music Festival, according to the ‘Summer Live’ edition of SPIN Magazine. An official announcement is not expected until Tuesday, but Austin 360’s Michael Corcoran also reported the news on his Twitter account late Saturday night.

West and Wonder will headline the Austin, TX-based festival alongside Arcade Fire and My Morning Jacket, both of which were confirmed late last week via the festival’s “lineup lottery.” Other confirmed acts include Fleet Foxes, Cee-Lo Green, Chromeo, Empire of the Sun, Delta Spirit, Smith Westerns, Hayes Carll, and J. Roddy Walston and the Business.

This year’s Austin City Limits takes place September 16-18 at Zilker Park. Three-day passes for the festival are sold out, but one-day passes will be available starting May 17th.
