But never underestimate Jay's work ethic: Billboard is reporting that the rapper is planning to hit the stage as a special guest on U2's 360 Tour in Australia.
The five-city tour will be the first concert promoted by the new Live Nation Australia. The outing will begin in Auckland's Mount Smart Stadium on November 25 and make its way to amphitheaters across the country, stopping in Melbourne, Brisbane and Sydney. It will conclude at Perth's Subiaco Oval on December 18.
Tickets will be on sale to the general public September 3, while U2.com subscribers will have the opportunity for a pre-sale. U2's summer leg of the tour was rescheduled after lead singer Bono suffered a back injury, pushing those dates to the spring and summer of 2011.
This won't be the first time Jay-Z and U2 have joined forces. Earlier this year, both acts, as well as Rihanna, performed their benefit song "Stranded (Haiti Mon Amour)" as part of the "Hope for Haiti Now" telethon. In addition to their charity song, Jay-Z and U2 also proved to be music heavyweights when they made the top 10 on Forbes magazine's list of the world's top-earning musicians.
