Lately, the Poosh founder has been very vocal about embracing her curves. In an Instagram live with Poosh COO Sarah Howard, the eldest Kardashian sister opened up about seeing comments asking if she was pregnant on an Instagram post. “So many of the comments were like, ‘Are you pregnant? Baby No. 4?’ … I could’ve taken that offensively … but I know that I didn’t look pregnant.”

“It’s very feminine to have curves and I embrace my body, so I didn’t take it offensively,” she added. “Instead, I wrote back, ‘Oh, let’s put the good blessings out there.’ Like, put out a good vibe.”

Earlier this month, the reality TV personality celebrated her birthday while self-isolating at home in Calabasas, California with her kids — sons Mason, 10, and Reign, 5, as well as daughter Penelope, 7½ — during the novel coronavirus pandemic. In the morning, Kourtney woke up to find a trail of flower petals from her room, courtesy of her daughter.
