Actor Gary Oldman has married for the fourth time in a secret ceremony in California.

The Dark Knight star, whose second wife was actress Uma Thurman, sparked speculation of an imminent engagement announcement after he appeared with Alexandra Edenborough at the Los Angeles premiere of The Curious Case of Benjamin Button in December.

But the pair opted for a low-key ceremony in California last week, with Oldman asking his agent Douglas Urbanski to be best man as he wed the 31-year-old jazz singer.

Urbanski says, "Yes, they were married in Santa Barbara. I was best man."

The British-born couple are now based in Oldman's adopted city of Los Angeles.
