Madonna & Guy mark big 5-0

POP queen MADONNA looked radiant as she stepped out with husband GUY RITCHIE to celebrate her 50th birthday.

Madge and British film director Guy, 39, put on a united front last night amid claims their eight-year marriage has hit the rocks.

She looked as good as ever as she draped herself in silver jewellery and held a diamond-encrusted handbag, which appeared to bear her own name for the bash at west London's swanky Volstead club.

And Guy looked like a typical English country gent in a green suit and blue tie.

An onlooker said: "Madonna looked fabulous for 50-she lit up the place as she walked into the club.

"They looked very happy. It wasn't just her necklaces and handbags which were sparkling-she was too."

Looks like the old girl could still be Crazy For You, Guy.
