Lady Gaga has said that she had her Oscars speech prepared since she was 14.

Speaking on US talk show Jimmy Kimmel Live!, the A Star is Born actress said that she began her rehearsals while working as a hostess to supplement her pocket money as a teenager.

"Sometimes no one would be coming in the restaurant, and I'd be standing there with nothing to do," she recounted.

''And I would just go, 'I'd like to thank the Academy for this tremendous honour. I've wanted to be an actress my whole life'. I would practise my acceptance speech and everyone at the bar would shout, 'That's never gonna happen'.''

The 32-year-old star won her first Academy Award last Sunday for Best Original Song for Shallow from A Star is Born.

What Gaga actually said on the night was: ''If you're at home and sitting on your couch watching this, it is hard work. I've worked hard for a long time. It's not about winning; it's about not giving up. If you have a dream, fight for it.

"It's not about how many times you get rejected or that you fall down or are beaten up; it's about how many times you stand up and are brave and you keep on going.

"Thank you so much to the Academy for this wonderful honour, to every person in this room, to Mark Ronson, Anthony Rossomando, and Andrew Wyatt, my co-writers.

"To my sister, my soulmate. My family is here, I love you mom and dad. Bradley [Cooper, director and co-star], there is not a single person in this planet that could have sang with me but you, thank you so much. Thank you for believing in us. Thank you so much.''
