That's actually more delusional than anything else lol. You don't employ a woman whose body is her career as a surrogate. And as a model, there is absolutely nothing to gain from being one. Brother. You hire a desperate 3rd world 18 year old as a surrogate. Then you fly her to america and have her live in your guest house. Everyone knows that.
You really think she's going to potentially ruin her body forever for someone else's baby? You're out of your mind dude.
No, it's her baby. No chance it's anything else. And because this is clearly the case, then we must conclude that whichever circumstances are required for it to be true are also true. If she 100% needs to be married to feel safe giving birth, then guess what? She's married. Sorry you had to find out like this lol.
One possibility is that she found some hot starving artist type and her hormones screamed at her that this is likely her last chance, so she just went with it. As a wealthy white woman in California, she has no reason to fear a custody dispute. Especially if she has more money than the father. That's an incredible power disparity to have as a mother, and she would know that.
I guess while we're at it, another possibility, and maybe the most likely, is that she went the Melania Trump/Anri Okita route, and leveraged her notoriety into a relationship with a billionaire who is 30 years her senior. Seems like a good exit strategy. She gets her baby, she can retire if she wants to, and if the relationship doesn't last, she gets a piece of his fortune because they had a baby together.
But a surrogate? Absolutely not.
