Liam Gallagher's band will go on stage before headliners Kasabian on June 12. The gig is the first festival appearance the group have confirmed.
Kings Of Leon and Foo Fighters are the other headliners for the event, which takes place on June 10-12. Pulp are also on the bill.
Speaking in this week's Christmas issue of NME, which is on UK newsstands and available digitally worldwide now, Gallagher said he believes Beady Eye's debut album 'Different Gear, Still Speeding' is as good as Oasis' 'Definitely Maybe'.
