As a surprise for his wife model Aleksandra, Russian billionaire banker Andrei Melnichenko has paid $3 million to have Jennifer Lopez sing at her 30th birthday party.

Their Harewood House, which has 12 bedrooms, a helicopter pad, a croquet lawn and stables, can easily accommodate the 60 guests, including his Chelsea boss Roman Abramovich, who have been invited to attend the birthday party, writes www.Hollywood.tv. According to a source, “J-Lo was booked because both Andrei and Aleksandra are fans of her. She is flying in specially from LA.”

Another source said “all week there have been lorry loads of stuff coming in. The marquee has been done out like a really plush nightclub. There are going to be acrobats and a huge fireworks display by the lakes.”
