Madonna rang in the big 5-0 with husband Guy Ritchie by her side at London hotspot Volstead on Saturday.

The pair — who recently denied rumors they plan to adopt another child from Malawi — were all smiles for the celebration.

The material girl glowed in a sheer black blouse with super blonde hair and tons of bling around her neck. Ritchie, 39, dressed dapper in a three-piece suit and stayed close to his wife of seven years.

Their behavior is a far cry from tense outings earlier this summer, when the couple were dodged by split rumors following Us Weekly’s exclusive report that Yankees slugger Alex Rodriguez had been making late night visits to Madonna’s NYC apartment.

In July, the Times of London confirmed that Madonna had consulted the same high-profile divorce attorney who worked with Paul McCartney. Us confirmed that Ritchie had sought legal advice from Forsters law firm in London.

So what did Ritchie get his wife for her birthday?

News of the World reported that he commissioned graffiti artist Banksy (Brad Pitt is a big fan) to design a portrait of Madonna for $900,000.

On Sunday, Madonna capped off her birthday weekend by hitting a gym in London.

Her Sticky & Sweet tour (following the release of her eleventh studio album, Hard Candy) kicks off in Wales on August 23.
