Lady Gaga admits that, contrary to public perceptions, she's actually quite an introvert.

The Daily Star quotes the singer as saying: “People think I’m really confident but actually I’m quite shy and insecure.

“I never want to talk to anyone at the big celebrity functions because I don’t know anyone and I’m shy and get awkward.

“I like my real friends around me so that’s why wearing the meat dress was so great because it stunk and no one wanted to talk to me.”

Gaga also explained that her latest single ‘Hair’ is an ode to her vast collection of wigs, which are her most prized possessions.

She said: “The song is about how, when you are young, the only way you can express your identity is through your hair.

“I went to a Catholic school with a uniform, so my parents would always say, ‘Go upstairs, brush your hair and change your clothes’,” she said.

“As you can imagine, I was very frustrated. So for me my wigs are every- thing.  It gives me the ability to transform as much as I can all the time."
