The 'RIP' singer told Digital Spy that she will play the "head girl" of a London racing crew in the Vin Diesel action sequel.
"They needed a head girl [for] the girl drivers of London town," she said. "They asked me, 'Would you mind being the leader of the pack in London?'
"I was like, 'Of course, I'd love to'. And I think it summed up a great year for me, life kind of changed last year, so I did feel like a cool little leader when I was playing that role."
Ora added that she will act as a race starter, coming "in and out" of the blockbuster for several scenes.
"I didn't actually have time to rehearse any stunts because I literally got asked the day before the whole set was finished," she explained. "I had to kind of come in and shoot it at the last minute."
Despite speculation that Ora stepped in to replace Rihanna in the film, the popstar said that she was unaware of the rumours prior to her casting.
"That's the first time I've heard of it," she said. "No, I don't know. I mean, I've never heard that."
"Wherever the world takes me. I would love to do a movie," she said before her acoustic performance at the exclusive Sony VIP reception at Mobile World Congress 2013, following the announcement of the Xperia Tablet Z.
"I'd love to do a whole soundtrack to a movie. I'd love to even have a feeling about what I can do. Because soundtracks to movies are really important and you know, the Drive soundtrack I thought was really incredible. I think it's a big deal to have a great soundtrack for a movie."
Fast & Furious 6, starring Vin Diesel, Paul Walker and Dwayne Johnson, will open in cinemas on May 24.
