He hasn't lost his temper and exposed his little sister to cyber-stalkers; rather he's just expressing his excitement on Snapchat.
The 29-year-old appeared to throw some digs at his family by posting dozens of Armenian flags - even though his sisters are the ones that aren't invited this time
This one is being hosted by Chyna's friend Sylvia Karapetian in Woodland Hills with around 60 guests in attendance... and only one of them named Kardashian.
A source tells Us that there will be approximately 60 guests at the Woodland Hills, California, celebration, including friends of both Chyna, 28, and Kardashian, 29, and that Chyna’s friends and family will be flying in to celebrate.
“There will be lots and lots of flowers,” the insider says. “The theme is neutral — lots of whites and grays and greens. There will be lots of music and food and drinks.”
Rob however showed his excitement when by sharing the news on his snapchat
'Baby shower Sunday can't wait!!' he exclaimed in an emoji-filled snap, filled mainly with Mexican flags.
He then followed it up with two more posts featuring no less than 53 Armenian flags, despite the fact the world's most famous Armenian family will not be there.
