The "In Da Club" hitmaker insists the three acts would have split an easy $100 million (£80 million) had the trek gone ahead, but Eminem didn't want to spend time away from his daughter.
"You do not believe how much money we would've made," he told Big Boy TV. "Em was like... There were so many dates at the time the way they laid it out that he was like, 'I just don't want to go on tour and come back and Hailie's grown.' "
50 Cent also recently revealed he and Eminem are working on new music, "He got some things, man. Still the highest-selling rap artist in the world. We're doing it now."
