Looking at this for a while a few things come to mind:

1. There's a likely chance theyve met in person before (as billionaires)
2. If he wanted to get any direct message to her it'd be a snap
3. His ego is so big he can't imagine that any woman wouldn't be enthralled by him, surely any who act repulsed are simply acting.
4. This post is not for her reaction at all, but for his fans to hype him up with reassuring tweets(?) of "he got her!"

All I can imagine now is that in some past meeting he being as cringey as possible brought up them having a child would have had brains and her looks. She laughs awkwardly and leaves as quickly as possible.
