I have the same birthday as Khloe. Yesterday I went for a lovely meal with just one friend I haven't seen in a while, followed by a lovely walk by the sea in the sun. I'm not active on social media.
Khloe shares approximately 60-70 posts on her story wishing her a happy birthday, plus shows off the usual ridiculously OTT and expensive tacky rose display. Does she not feel embarrassed about this level of attention!- everyone has birthdays, and apart from a milestone like 30/40/50 (maybe!) no one gives a tit about your birthday after the age of about 25.
I just find the massive gulf between the Kardashians and normal people endlessly bemusing yet also entertaining. Hey, isn't that how they makes their millions!
