The Bajan beauty’s jet set lifestyle means she’s barely able to get any shut eye. Back in 2017, Rihanna admitted to Vogue Paris that she can only get in three to four hours sleep a night.

It’s passion for her craft which often leads to sleepless nights for the ‘Poker Face' singer. In a 2010 interview with OK! magazine, Gaga said: "My passion is so strong I can't sleep - I haven't slept for three days. I lie in bed and try to pray and breathe. I have a very overactive mind. I'm the sort of person who would never take medication to calm myself. It's maddening. But I love what comes out."
