Lady GaGa is Stefani in bed

You can call Lady GaGa ‘GaGa’ – unless you’re in her bed.

The singer, real name is Stefani Germanotta, says she would be “freaked out” if someone called her GaGa in the bedroom.

Asked by 60 Minutes interviewer Anderson Cooper how he should address her, she said, “Call me GaGa. Some people do call me Stefani. Especially in bed.”

“You don’t want somebody yelling out ‘Lady GaGa’ in the throes of passion.” Anderson replied.

GaGa, who is dating Luc Carl, laughed and replied “No. Especially then. No. That would freak me out.”

The 60 Minutes special featuring Lady GaGa is due to air in the US on Sunday.
