Days after she headlined the Super Bowl LVII Halftime Show, British Vogue reveals Rihanna, A$AP Rocky and their infant son as March cover stars. In the cover story by Giles Hattersley, Rihanna, famed for keeping "rockstar hours," explained that she's learned a lot about work-life balance in her nine months as a mother. "You come to have a different respect for moms and dads," she said about the all-night work sessions in her past. Other tidbits from the interview: The baby is sleeping through the night. Rocky wanted a son and the birth was "beautiful." And no, she still doesn't reveal his name -- or say when her next album is coming. 📷: British Vogue
