The rocker reignited his war of words with Williams this week (begs17Jun13) when he labelled the pop star a "fat idiot" in a U.K. radio interview.
Williams has now hit back by branding Gallagher's rants more interesting than his songs with rock band Beady Eye.
He says, "The interviews are better than the records at the minute. I really enjoy the interviews. Liam is like an episode of (satirical Tv show) Star Stories."
The former Take That singer also made a dig at Gallagher's latest Beady Eye album Be, suggesting the tracks would be better if Liam's brother and ex-Oasis bandmate Noel was on board.
He adds, "The production is really good. There are a couple of tunes that would have been f**king amazing if they had a chorus. Flick of the Finger, nearly a great tune. Start Anew (would be good) if that had a chorus, but there is no chorus. They are missing The General (Noel)... When you listen to them you think, 'Please put a chorus in - it will be brilliant'. They are not going to have a character brave enough to tell Liam that."
Williams first fell out with the Gallagher brothers in the 1990s when the siblings referred to him as the "fat dancer from Take That".
