Russell Brand wears a skull-patterned Christmas jumper on US TV

He also told how he and his wife Katy Perry have bought a 'sexually active' cat and how he is learning to drive.

He also says they enjoy living in LA even though the 'phone service isn't as good' and his pet cat he has brought over from London 'is a bit grumpy'.

Talking about his unusual attire, Russ said: 'I was planning to look festive.

'When I put this on, festive was the word I was aiming for.

'Would Christmas be complete without a skeleton?

'The answer is no.'

Talking cats, he said: 'I bought over one cat, and my wife had a cat, and we've bought a cat to unify them and that cat is like a spoilt child of second marriage.

'Also, that cat became sexually active, not with us, it made it clear that it was ready for sex. It puts its tail to one side and makes these noises, which frankly I don't find appealing.'

Talking about learning to drive, he said: 'I thought I should learn to drive a car after seeing your cars, Jay.'
