The Bad Romance hitmaker, real name Stefani Germanotta, told fans at a Los Angeles gig on Sunday night (31May15) that there is no truth to reports she is expecting a child with her fiancee Taylor Kinney.

As she performed alongside legendary crooner Tony Bennett at the Hollywood Bowl venue, she revealed the veteran star had taught her to embrace her body and she playfully grabbed her thigh while explaining her extra pounds were not baby weight.

She told the audience, "I'm getting a little older and many people think I'm pregnant but I tell them, 'I'm just almost f**king 30'... Tony's taught me (that) you can live your life and feel the same every single day forever... Me on the other hand, I'm having a more difficult time with things. (I've got a) little more (weight) here and there."

Lady GaGa and actor Kinney have been dating since 2011 and he popped the question to the singer on Valentine's Day (14Feb15).
