Used to work in PR years ago before I had kids. A few things I remember:
Emelie Sande: really lovely, makes hand made cards for people and friends
Ella Eyre: EGO! Apparently at a label meeting she said “ask yourself, would Beyoncé do it” no wonder she doesn’t have a career
David Haye: sleazebag. Made girls uncomfortable.
Ewan McGregor: nice bloke but a bit tight. Very flirtatious.
Rita Ora: known as a man eater (all the more power to her really!)
Miriam Margolyes: completely batshit crazy in the best way. She is as eccentric as you see on television. No filter when she speaks.
In my experience, it’s the smaller celebs Like reality stars that have the biggest attitudes.
