British jazz sensation Jamie Cullum is baffled by reports he is dating MARTINE McCUTCHEON - because he has never met the UK singer/actress.

The 26-year-old musician has been repeatedly linked to LOVE ACTUALLY star McCutcheon, but insists he saves all his love for his lawyer girlfriend ISABELLA CANNELL.

And the rumours have led him to believe McCutcheon must be dating his doppleganger Elijah Wood.

He says, "Martine's a mystery because I've never even met her. So she must be hanging out with someone who looks like me, perhaps Elijah Wood.

"I'm happy with Isabella."
