TORONTO - GUY Ritchie already celebrated a milestone birthday this year: wife Madonna's 50th. So the British filmmaker isn't thinking much about his own milestone birthday on Wednesday.

'I've thought less about my 40th birthday than almost any other birthday,' said Ritchie, who was in Toronto to promote his new film, RocknRolla, which opens October 8.

'I'm not sure if that's kind of an unconscious thing. But I have no plans. So I hope someone's organising something for me. But don't expect a Madonna-sized bash,' he said.

'I paid for Madonna's 50th,' Ritchie said of his wife's party.

'And unless someone's prepared to pay the same amount for mine, it's unlikely to be as big.'

Besides, the writer-director has kept quiet about his big day, said Mr Gerard Butler, one of the stars of RocknRolla.

'He didn't tell anybody,' Butler said.

'I'm thinking he doesn't want anybody to know he's that old.' Ritchie still wants gifts though: 'Just lots of accolade and money.' -- AP
