LONDON - Oasis singer Liam Gallagher says he is suing his estranged brother and former bandmate, Noel, for saying his hangover forced the rumbustious Brit rockers to cancel a concert.

Bad blood between the brothers has frequently made headlines. When Noel left the band in 2009 he said it was because he couldn't work "a day longer" with his brother.

Liam is disputing comments Noel made last month alleging that Liam pulled out of the 2009 V Festival due to a hangover.

Liam said in a statement Friday he wants an apology and for Oasis fans "to know the truth" about what happened -- laryngitis prevented him from performing the gig.

Liam Gallagher's spokesman confirmed the singer had issued a writ at the High Court in London against his brother.
