Britney Spears uses stage persona to overcome extreme shyness, Beyonce underwent counseling to deal with childhood fame

Britney Spears overcomes her painful shyness by cutting loose and putting on fierce performances onstage. "I'm very sensitive and sometimes I just want to run away because I'm a very shy person... I think it's healthy to be able to put on the persona of being confident," the singer said.

"I think it's an escape because honestly with how shy I really am, I don't think it's healthy," she shared. "(Performing is) a boost to my confidence. It's like an alter-ego type thing. Something clicks and I go and turn into this different person", (Music News).

Similarly, Beyonce's mum Tina Lawson put her and her other daughter Solange in counseling when they were kids to help them cope with Beyonce's growing fame (Music News).
