For some reason Carrie Johnson popped up on my Instagram suggestions and I had a look.
One the one hand I had the same response i have to MM on Instagram: they both married flawed famous men, they are utilising that to promote themselves, and I don't understand the drive to share their personal lives, and their children's, for what? What do they gain through this self promotion?
BUT
The one big difference was Carrie Johnson made her life look real, full, and aspirational (apart from having to be married to Bozo. ) her photos show days out with the kids, picnics with friends, weekends away, her with girlfriends and other friends with kids, big family lunches at home, drinks with friends, a lovely homely but obviously expensive house and garden etc etc. It looks like a full life.
Whereas Ms Instagram is weird adverts combined with forced looking photos or skits of an empty looking life. She cannot portray a full life of friends and family because presumably she doesn't have one. So we get these weird sad 'here's me being manic on my birthday' posts.
