I think she gets a lot of comments about how hot Jesse is (fair tbh
) so maybe she doesn't want to draw attention to him? Especially when he obviously doesn't want to be on camera loads. She didn't talk much about Chloe's wedding in videos either.
Looking from a slightly different perspective, if she doesn't talk about the marraiges of her siblings then no doubt there will be so much other personal stuff she doesn't post online, which I think is good tbh! It's better to set up boundaries and be able to enjoy your personal life without vlogging/instagramming/tiktoking every minute of your life!
