Jay-Z and Beyonce at the 2010 Tony AwardsJay-Z and Beyonce are more than just hip-hop’s power couple, they are money-making machines … and most recently, became world record holders.

The couple have been named the Highest Earning Power Couple in the 2010 Guinness Book of World Records, clocking an impressive $122 million combined through June of last year, which gave them the #1 spot on Forbes’ Hollywood’s Top Earn Couples list earlier this year.

Obviously record sales make them money, but the Carter’s continue to bring in dough through touring, and other business ventures — including clothing lines and endorsements.

According to Forbes, Beyonce netted $87 million in 2009 from several businesses including her clothing line House of Dereon. Jay’s bread came from his 40/40 Club franchise which boasts locations around the country, his Rocawear clothing line, and endorsement deals, bringing in $35 million of their collective earnings.

Other musicians included in this year’s Guinness Book of World Records include Lady Gaga who holds the record for the world’s “Most Searched for Female On the Internet,” Michael Jackson who reigns as the “Most Searched for Male on the Internet,” and Susan Boyle, who earned three titles including “Oldest Artists to Reach No. 1 With a Debut Album.”
