As BBC News reports, the Gallaghers are at it again. This time, Liam-- who currently fronts Beady Eye, a band featuring everyone from Oasis except his brother-- is suing Noel for "questioning [his] professionalism" by telling journalists at a July press conference that Oasis pulled out of a 2009 V Festival gig because Liam was hungover. (At the time of the festival, the official explanation was that Liam had laryngitis, which he maintains was the truth, according to the BBC. Oasis officially called it quits later that year.)According to the BBC, in a statement, Liam said he had "tried to resolve [the situation] amicably but have been left with no choice but legal action." The requested settlement? "All I want is an apology."

Noel made the offending comments while promoting his album Noel Gallagher's High Flying Birds. According to the BBC, he said the V Festival cancellation was one of the reasons Oasis split. So far he hasn't made a public reply to Liam's suit. While we wait for that apology, a video of the guys in happier times:
