Lady Gaga suffers from stage fright during her Oprah appearance

It seems Lady Gaga is not the tough cookie we had her down for.

After admitting to suffering from bouts of insomnia a few months back, it’s now come to light that the singer also has a mild dose of stage fright.

According to US sources the star refused to walk the red carpet at the Met ball (although her sequined nearly nude playsuit, which she performed in, wouldn’t have screamed shy to us) and then locked herself in her dressing room before appearing on Oprah.

A source told the New York Post: “She literally wouldn’t come out.”

After friends and music execs failed to coax her out artist Terence Koh and Oprah tried and succeeded in getting the star on-stage.

And it seems the stagefright was short-lived. When Gaga got on stage, she told the 700 guests that co-host Anna Wintour had asked her not to swear – which she did anyway. Glad to see you got your fight back Miss G.
