According to reports, Jay-Z is going to make $1 million to perform at the launch for the new Cosmopolitan Resort and Casino in Las Vegas.
Coldplay are also playing at the $4 billion resort that night, and sources say Gwyneth Paltrow will be in attendance. Shocking that they'll be together for once!
Chris will join Jay-Z in the line-up to perform in front of 2,500 partygoers at the 2,995-bedroom hotel.
Keep in mind, Jay Z and Beyonce were just named the highest-earning couple in showbusiness last year, earning $100 million between them from June 2008 to June 2009.
So this is like pocket change for them....must be nice!
