Since Rihanna's Super Bowl performance over the weekend, we've known the superstar is pregnant again. Now the singer presents herself as a happy glamor mum with her first child in British Vogue.

Rihanna shared photos from the shoot with her nine-month-old son on her Instagram profile. "My perfect baby!!!" Rihanna comments on a close-up of her firstborn, who will become a big brother later in the year.

Additional photos show mum and son together on a bed upholstered in shiny red fabric. "It's crazy that my two babies are in these photos and Mommy didn't know about it," wrote Rihanna, who appeared to have no idea she was pregnant again at the time of the shoot.

The Vogue cover features Rihanna and her son as well as her husband, rapper Asap Rocky. He is holding their first child, whose name the two have not yet revealed, in his arms.

In the magazine's March issue, Rihanna opens up about her role as a mother and her relationship with the 34-year-old. "We're best friends with baby," says Rihanna. "We need to be on the same wavelength, but our relationship has always been like that. Everything changes when you have a baby, but I wouldn't say it did anything other than bring us closer."

On Sunday, Rihanna appeared at the Super Bowl halftime show and made the headlines, while the Kansas City Chiefs' win almost took a backseat. Her costume revealed a baby bump, and the family will grow to four over the course of the year. A spokeswoman for Rihanna confirmed the pregnancy after the Super Bowl final.
