Lady GaGa doesn't care what Madonna thinks about her.

The 'Applause' hitmaker, who has never tried to hide her issues with the legendary singer, thinks Madonna is secretly ''aggravated'' that their feud doesn't bother her.

Asked if their dispute, sparked by her 2011 single 'Born This Way' bearing similarities to Madonna's 'Express Yourself,' is fuelled by jealousy, Gaga told Howard Stern on his SiriusXM show in New York on Tuesday (12.11.13): ''There's not so many ways you can interpret it. To me honestly I think she's more aggravated that I'm not upset that she doesn't like me. Because I don't care that she doesn't like me. No, I don't care.''

She later added: ''It's silly. There's always this p**sing match, 'Did she take her torch?' [and] 'Is she the new her?' 'Is she going to outlast her?' ... There's this thing with some people that I'm a threat to the throne.''

The 'Bad Romance' singer, 27, who recently ended her long running feud with 'Fashion Police' co-host Kelly Osbourne, also insists her fights with other celebrities aren't really about her.

She said: ''All the feuds usually ... [are about] somebody is feuding with themselves about me.''
