Beyonce

Even Beyonce hasn’t had it easy, with the ‘Cowboy Charter’ chart-topper previously admitting her touring schedule and the tribulations of travel took a toll on her mental wellbeing.

She said: “It was beginning to get fuzzy - I couldn't even tell which day or which city I was at. I would sit there at ceremonies and they would give me an award and I was just thinking about the next performance.

“My mother was very persistent and she kept saying that I had to take care of my mental health.”
