Rihanna, 34, who is expecting her first child with boyfriend A$AP Rocky, revealed she is in her third trimester and while she sometimes feels the "glow", she has days when make-up helps her "feel like a real person".
The singer told “Elle” magazine: “There's a pregnancy glow. There's also those days, girl. Especially in the third trimester where you wake up and you're like, oh, do I have to get dressed?
“Make-up for sure helps you feel like a real person. I just focused a lot on moisturising and on contouring. The face gets a little round and chubby. The nose starts to spread.
“Everything is a challenge, from getting dressed and how you're going to do your make-up. But I like challenges. I like things that force me to be creative and create in new ways.”
The “Diamonds” hitmaker is a huge “Real Housewives” fan, and she pointed to Heather Dubrow and Teresa Giudice's respective approaches to motherhood.
She praised Heather's ability to be "so chic while being a mom", and letting her kids "be who they are".
She added: "And that's really inspiring to me. But Teresa from 'Jersey' does not play about her kids.
"She will flatten you about those kids. And that resonates with me a lot because I feel like that's the type of mom I'm going to be. Psycho about it."
The Fenty boss previously revealed she is enjoying experimenting with her pregnancy style.
She said: "I’m enjoying having not to worry about covering up my tummy. I like it. I'm enjoying it.
"If I feel a little chubby, it's like, whatever! It's a baby!"
Cosmetics and fashion mogul Rihanna also explained that make-up has helped her to feel more confident during her pregnancy.
She confessed: "Right now, being pregnant, some days you just feel like, 'Ugh, I just want to lay here on this couch all day.' But when you put on a little face and a little lipstick, you transform.
"You put some clothes on, and it's like, when you look good, you feel good. I've heard that for a very long time, but it's true. It really can get you up off that couch and make you feel like a bad b****."
