Beyoncé reportedly spent $5 million on her husband Jay-Z’s latest birthday gift.

Jay-Z, who turned 43 on Dec. 4, received a luxury Hublot watch with over 1,000 diamonds on it.

A source told the Daily Star, “Beyoncé will always buy Jay the best gifts money can buy. Money is no object to her.

"She knew he would love the Hublot Big Bang watch. It’s the ultimate timepiece, a mixture of extravagance, luxury and bling.

"Jay Z is a huge watch collector and was very excited when he was given the gift. He can’t wait to start flashing it around. It is absolutely stunning. In Beyoncé’s defence, what do you buy the man who already has everything?”

This is not the first time Beyoncé has lavishly spent her money. The singer, Jay-Z and their daughter, Blue Ivy, spent August at a $43.5 million estate in the Hamptons.

The self-proclaimed diva and her rapper husband, who, Forbes reports, jointly earned more than $70 million last year alone, rented out the 11-acre property for $400,000, according to the New York Post just for one month.

Jay-Z told Oprah earlier this year, "at the end of the day, I just know I'll probably have the worst, spoiled little kid ever." The New York Post reported that the rapper spent $600,000 on a solid-gold, handmade horse from Japanese jeweler Ginza Tanaka for Blue Ivy, and Beyonce and Jay-Z reportedly spent $1.5 million on gifts for their now six-month old child.

On his rap song, "H.A.M.," released last year, Jay-Z raps, "You ain't got my lady's money!" It's true.

Beyonce earned an estimated $35 million in 2011, reported Forbes. The Daily Mail states that she spent $1 million on her Mercedes van, which is said to have a full bathroom with a shower, sink and toilet. She also bought Jay-Z a luxury plane for this Father's Day, worth a whopping $40 million, other news reports said.
