Beyonce spent more than $5 million on her birthday present for hubby Jay-Z; She bought her man a luxury Hublot watch named the Big Bang-- with 1,282 diamonds on it.

A source said: "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?"
