Madonna's husband Guy Ritchie paid tribute to her at her 50th birthday celebrations on Saturday.

The director threw a lavish $200,000 party for 90 guests to celebrate his wife reaching the landmark age at the weekend and, in an emotional speech, spoke of his love and pride for the singer.

Madonna has been forced to postpone her 50th birthday celebrations after twisting her ankle.

The "4 Minutes" singer - who reaches the milestone age on Saturday - was set to throw a lavish party at her country estate in Wiltshire, England, but has now postponed the festivities after suffering an injury during rehearsals for her forthcoming world tour.

Heather Mills is looking for another U.S. home. The former model - who won $50 million in her divorce settlement from Beatles legend Sir Paul McCartney - recently splashed out over $5 million on a New York apartment and is now hoping to buy a property in West Hollywood or Beverly Hills.

However, Heather's search has so far been unsuccessful and she has reportedly been losing her temper with real estate agents who are ignoring her strict budget of no more than $1,000,000.
