Rihanna
The Umbrella hitmaker has had several chart-topping hits but confessed that she is "shy" and still gets stage fright.
She said back in 2016: "And still you wouldn't believe, but still I get shy and awkward and (have) stage fright.
"I've always been that way, but... when you realise that nothing is wrong, even if it's awkward, it's not wrong... you kind of just are OK.
"Like you know it might be awkward for people or people might not understand it, but you're fine. I wouldn't change anything. I have to stay the same."
