Lady Gaga is dull in real life

London: She is known for her outlandish clothes and onstage antics but in real life pop star Lady Gaga is boring.

The eccentric singer has been nicknamed as `Lady Dull Dull` by her tour crew because of her off-stage persona.

The 24-year-old star, whose real name is Stefani Germanotta, prefers a more comfortable and casual look when she is off-duty and likes to slip into baseball caps and sweat pants, Contactmusic reported.

"She gets all comfy in sweats and a baseball, then becomes the easygoing gal we jokingly call `our den mom`. Another nickname we have for her is `Lady DullDull`, because she looks just like any one of us," a tour insider said.

Despite her normal life off stage, Lady Gaga has no desire to ditch her public persona, which has become a trademark of her music.

"If I were to ever, God forbid, get hurt onstage and my fans were screaming outside of the hospital, waiting for me to come out, I`d come out as Gaga. I don`t even drink water onstage in front of anybody, because I want them to focus on the fantasy of the music," the singer had said.
