Cardi B cancelled her spring and summer tour dates back in April because of her pregnancy. Now she's posted a message on Instagram explaining her decision to cancel her upcoming tour with Bruno Mars. "I thought that after giving birth to my daughter that 6 weeks would be enough time for me to recover mentally and physically," Cardi wrote. "I also thought that I'd be able to bring her with me on tour, but I think I underestimated this whole mommy thing." Read Cardi's message below in full below.

Bruno responded to Cardi with a message of his own. "Most important thing is you and your family's health," he wrote. "I know the fans will understand. You are absolutely doing the right thing." He also said he'd "play 'Bodak Yellow' every night in your honor." Read Bruno's message in full below, as well.
