Lady GaGa's father cried when she got her driving licence.

The 'Perfect Illusion' hitmaker has revealed she was left feeling ''embarrassed'' when her father Joe got tearful when she passed her test.

Speaking in James Corden's Carpool Karaoke segment, she said: ''It was so embarrassing - my whole family came with me to the DMV (Department of Motor Vehicles). My father cried when I got my driving licence. I was like, 'Dad, I'm 30!' And he was like, 'I'm just so proud of you.'''

The 30-year-old singer was thrilled to have passed her test in July, taking to social media to express her excitement.

Sharing a picture of herself behind the wheel, she wrote at the time: ''Thelma and Puhleaaaze (And yes I FINALLY got my license after years of driving w an adult present and a learners permit) ... I'M FREE ... Rollin w the homies.(sic)''

In another post, she shared a picture of herself jokingly falling out her car onto her knees, captioning it: ''And after I passed my driving test. PRAISE HIM (sic)''

Meanwhile, the singer believes she has healed her father's broken heart with her new album 'Joanne', which she named after her late aunt who died of lupus at just 19-years-old.

She said: ''[The first time I played 'Joanne'] I looked over at him and he just looked at me like, 'How did you know that? How did you know that's what I wanted to say?'

''I never got to meet her but I always felt very connected to her my whole life. I never was able to truly understand why my father was so sad. There was something inside of him like a loss or a trauma that I just couldn't perceive of. So I wanted to make a song that would be really healing to my dad.''
