The singer confessed that her dad Joe Germanotta often asks her to wear more normal clothes.
"I look the same during the day as I do on stage," GaGa said, according to The Sun.
"My father is still like, 'Can't you just put this on?' Some of it he just can't handle."
The singer has spent the the past few days organising the setlist for her next tour. She tweeted on Friday that she will preview the stage on Tuesday.
GaGa has previously admitted that she will never be caught wearing casual clothes.
"I think you should look nice all the time," she said. "When I meet celebrities and they're in casual clothes, I'm always like, 'Whaaat?' I don't mean to be judgmental, but it would do them better to be who they really are, all the time."
She recently revealed that she would like an Italian sperm donor.
