Lady Gaga's mum is joining her daughter on her tour bus to tame the pop star's wild lifestyle, according to reports.
The Sun said that Gaga's mum Cynthia Germanotta, 56, wants to ensure her daughter, who collapsed last year, looks after herself.
A source said: "She may be one of the biggest, and strangest, pop stars in the world but her relationship with her parents is very traditional. She is from a typical loving Italian-American background and her family have normal parental concerns "
The Sun said Gaga's mother is worried that the US singer drinks too much and doesn't eat enough while on the road.
Gaga - real name Stefani Germanotta - collapsed on stage while on tour in Japan last year.
She has also revealed that she has been tested for the potentially fatal disease lupus.
The star has previously revealed while opening up about her health: "I have heart palpitations and... things. But it's OK. It's just from fatigue and other things."
