Madonna 'Disappointed' With Birthday Celebrations 8/19/08

Madonna was left disappointed after her 50th birthday celebrations on Saturday (16Aug08) when several of her guests failed to turn up.

The Holiday hitmaker hosted a lavish party at the exclusive Volstead nightclub in London's West End.

It was attended by many of the star's family and friends - but Madonna was allegedly upset about the no-shows.

She reportedly told guests, "I'm really disappointed. "There are a lot of people who are not here tonight, but thanks to everyone who did make it."

The singer's daughter, Lourdes, played a song from hit musical Fame on a grand piano at the club and husband Guy Ritchie presented the pop star with $500,000 (£250,000) worth of jewellery.
