Kourtney addressed pregnancy rumours just last month as well when she shared a similar revealing photo of herself to Instagram.
Though she shut down the claims, the Keeping Up With The Kardashians star did give a subtle hint that she'd love to add one more to her brood.
"Put the blessing out there though 🙏🏻," she replied to a follower who asked, "are you pregnant?" before another added, "Nope, wish she was."
Kourtney shared a heartfelt dedication to her three kids on Mother's Day, sharing a throwback holiday photo to mark the special day.
"My biggest blessing, the three that have given me purpose, make every experience better, test me, teach me, and remind me of who I am in the truest sense, their mother," she captioned her Instagram post.
