On Jan. 27, the model, 26, posted a photo of herself wearing black lingerie along with the caption, "6 weeks postpartum. Loose skin, tight friendships."
This isn't the first time that April has posted a lingerie pic after giving birth. The mom of three posted a similar photo to her Instagram Story six weeks after she welcomed the couple's second child, a baby girl named Lola Alain, in 2019.
April and Robin, who got engaged on Christmas Eve in 2018 after going public with their romance at the Cannes Film Festival in 2015, are also parents to Mia, 2. The "Blurred Lines" singer also shares son Julian Fuego, 10, with ex-wife Paula Patton.
April regularly posts about her family life with her children and Robin. Earlier this week, she shared a sweet photo of her and Luca to Instagram, along with the caption, "My handsome boy."
She also posted a photo of The Masked Singer star and his new son, writing "My boys" in the caption.
April announced she was expecting her third child back in October 2020 with a joke about how routine her pregnancies have become.
"Sorry we can't hang out, there's a pandemic and I'm pregnant … again," April wrote on Instagram in the caption of a beach photo that showed off her belly. "We love consistency."
While she happily showed off her post-partem lingerie look, April was proud of her pregnancy bod, too. She posted a nude selfie to Instagram in December, just weeks before she was ready to give birth to Luca. "Baby mama," the model wrote.
Now, she's a baby momma 3x!
