No one has done more to make pregnancy cool than Rihanna – showing off her baby bump everywhere from the Superbowl to the Oscars to last week’s Met Gala. And we can expect a lot more of the same, as the singer tells friends she loves being a mum so much, she’s planning to do it another eight times. The superstar, whose second baby with A$AP Rocky is due later this year, says she wants a ridiculously huge family that will include biological children, some via a surrogate and a few more she’s hoping to adopt.

“Rihanna has been so blown away by the motherhood experience,” says Closer’s source close to the 35-year-old, who unveiled her latest pregnancy while performing at February’s Super Bowl. “She always used to say she wanted three or four kids, but as soon as she had her son that number doubled – now she’s talking about having ten! Motherhood is the best, most rewarding thing she’s ever done, so her feeling is, why stop at just a few? Yes, they’re about to welcome their second baby in the space of only two years, but they’re already talking about the next one and laughing about being surrounded by a huge family as they grow old together. They both say ten is the magic number for the ultimate perfect brood. They have so much love in their hearts and feel like this is their destiny.”

Last week the Umbrella hitmaker blew fans away on the red carpet of the Met, wearing a Valentino white gown with a silk cape, embroidered with flowers and a 16-foot train. The cape apparently took 30 seamstresses to create, featuring 500 petals, 25 leaves and 30 Camellias. Fans watching at home couldn’t get enough, with one tweeting, “Rihanna carrying the whole Met Gala as usual.” A second added, “She slayed that!” while one more said, “Love how she’s serving even as she walks”. Others loved the bridal theme, writing, “This is what I imagine her wedding to be,” while many more loved how much the look emphasised her pregnancy, writing, “The outfit got so much cuter when she took off the coat and showed off the bump.”

Rihanna continued to embrace her bump throughout the week, attending billionaire Alexandre Arnault’s birthday party at Cipriani Soho, in a fur crop top from designer Loewe. Days later she enjoyed a date night with Rocky, 34, in New York, wearing just a mesh black and white bralet that again showed off her stomach. But we’re told not all ten of these planned children will involve a bump.

“The plan – if they’re lucky and healthy enough – is for them to have two more babies by the time Ri’s 40,” says the insider. “Then they’ve talked about moving onto other options like surrogacy and adoption in later years.” Rihanna has revealed in the past that she’s open to adopting, saying in one radio interview back in 2010, “ I do want to become a mum one day. Even if I have to adopt, I want to be a mum.” And it’s clear she’s enjoying the whole experience. Speaking recently about her firstborn, whose name she’s yet to reveal, Rihanna confessed she’s “in love” with her son, who will turn one later this month, continuing, “I’m obsessed and I don’t even feel guilty about it.” She added that her second pregnancy has been a lot easier, saying, “It’s so different from the first one. No cravings. Tons of nausea. Everything’s different, but I’m enjoying it. I feel good. I feel energetic.”

The megastar has always talked freely about her plan for a big family, previously saying she wanted three or four kids. Earlier this year she amended that, saying she is now, “down for whatever.” She explained, “I would like to have more kids but whatever God wants for me, I’m here. I’m open to… Girl, boy. Whatever.” She went on to say how much she and Rocky have bonded with their child, saying, “We’re best friends with a baby,” and saying, “We have to be on the same page, but we’ve always kind of had that in our relationship. Everything changes when you have a baby but I wouldn’t say it’s done anything but made us closer.”

She also gushed about her “favourite part of the day” with her son, saying, “Oh my god, the mornings, like, seeing his morning face! Seeing a baby with, like, little bags and waking up and they’re just, like, startled. They’re trying to figure out where they’re at. It’s the cutest.” Rocky has also talked about his dreams for their family, saying “I will always remind my children to never lose their imagination, even as adults, no matter what.” He went on to say he enjoys watching kids shows, including Teletubbies and Peppa Pig, adding, “I hope to raise open-minded children. Not people who discriminate… I just want a cool child with cool parents.”

And friends say neither of the musicians are frightened by the huge job ahead of them. “Ri’s not fazed at all by the demands of having lots of children,” says the source. “She loves being a mom more than anything and has a ton of support from family and friends, as well as nannies when they’re needed. She feels like she has way more love to give and obviously has more than enough money. It helps that she’s having a great second pregnancy – it’s been such smooth sailing. She feels incredible and has even told people she’s really sad it’s going by so fast. It wouldn’t surprise anyone if she got pregnant again right away after having this one. She’s totally baby crazy!” Rihanna – who is from a large family herself, with two brothers, one half-brother and two half-sisters –  has shared how much she’s loved the experience of being pregnant – particularly when it comes to the fashion. “I’m enjoying not having to worry about covering up my tummy,” she said during her first pregnancy. “If I feel a little chubby, it’s like, whatever! It’s a baby!” In another chat, she said she loved being “rebellious” when it comes to what she wears, explaining, “When I saw women dress during their pregnancy [in the past], I’d think that that was the only way. So I challenged myself to push it further and really just have fun.”

Friends say this has been the happiest of times for Rihanna, who started dating Rocky three years ago, after a long friendship that dates back to 2013, when he joined her Diamond Tour. “They’re madly in love and on a real high right now, talking about their plans for the future,” says the source. “Rocky’s all for having a football team of a family – they can’t think of a more beautiful scenario! Of course, he’d never push Rihanna into having a bunch of kids but she’s made it clear it’s what she wants, so he’s more than happy to do his part! He’s so proud of Rihanna and their family and has been bragging about how they’re just getting started. They’ve even been dropping hints that they’re finally going to take the plunge and get married soon… This is a very happy time for both of them.”
