Blur are set to headline both Oxegen and T In The Park this summer.
The recently reformed Britpop group join Kings Of Leon and Snow Patrol, who will top the bill at both festivals.
Damon Albarn and Co will join Bloc Party, Katy Perry and The Script at Oxegen, which was voted the Best European Festival at last year's UK Festival Awards.
The 'I Kissed A Girl' singer Katy Perry will also perform at T In The Park but she is the only other name confirmed aside from the headliners.
Traditionally both festivals share the same line-up.
Oxegen 2009 will take place at Punchestown Racecourse, County Kildare from 10-12 July.
Tickets go on general release on Friday 6 March at 8am. However those registered on the official website can take advantage of an exclusive pre-sale from Wednesday 25 February.
T In The Park 2009 will take place at Balado, Kinross-shire in Scotland from 10-12 July.
General tickets are yet to go on sale.
