It is entirely possible she has had a kid or two and just kept that private. Some models double down on the ability to benefit from Preggo content, some do not.
I could understand someone keeping that private, or at least quiet. It is none of my business if she did or did not have kids. She also did have some time away from the spotlight where she could have had a kid off radar.
Still, it does seem a lot of her thicness has come on the past few years and she has been somewhat consistent with regular content during that time.
Either way... she is smokin hot.
