Cardi B Insists Rihanna Doesn’t Need Motherhood Advice As It ‘Comes Naturally’ Cardi B was stopped by TMZ recently and asked if she had any parenting advice for Rihanna. Cardi told reporters, “It really comes naturally. So many people give you advice. Once (the baby is) in there, that mother instinct comes out,” said Cardi. Cardi is the mom of two, three-year-old daughter Kulture and eight-month-old son Wave – with her husband Offset of the group, Migos. Rihanna announced her pregnancy in February and is expected to give birth later this month. What was the worst piece of parenting advice you received?
