Pete Williams is unimpressed at comments that Robbie, 37, made saying his rude language all stems from his upbringing.
According to UK newspaper Daily Mirror, Pete said: 'He did grow up in a pub for the first few years, but it wasn't rough. He didn't see or hear any swearing as far as I'm concerned.
'I don't swear ever, it's not in my vocabulary so I don't know where he got it from.'
Robbie was criticised for his swearing at a Take That gig where he came out on stage saying: 'I can't believe you're f***ing here.'
