Jay-Z is suing a children's bookstore.
The 49-year-old rap star - who is one of the wealthiest people in the music business - has decided to take legal action against the store in Sydney for using his image and lyrics, according to the New York Times newspaper.
It's claimed that the row centres on a book called A B to Jay-Z, which re-jigs a line from the rapper's chart-topping hit 99 Problems.
The reworked line from the record reads: "If you're having alphabet problems I feel bad for your son, I got 99 problems but my ABCs ain't one."
