Vin Diesel's "Fast and Furious 7" is expected to be a huge hit when it hits theaters in 2015.

The movie will star Diesel along with Dwayne "The Rock" Johnson, Michelle Rodriguez, and the late Paul Walker who has been digitally added to some scenes in the movie.

In a recent interview with SkyrockFM, Diesel was supposed to share some juicy details about his new movie "Guardians of the Galaxy."

But, the biggest surprise during the interview was when Diesel accidentally revealed about Australian rapper Iggy Azalea's stint in "Fast and Furious 7."

"Iggy Azalea and I just worked together two weeks ago," he said.

"I guess you're the first person to know this.. we cast her Fast And Furious 7...She had a cameo in it."

The buff actor was then asked to choose a song to dance to during the interview. And without a doubt, Diesel chose Iggy Azalea's "Fancy."

"I'm going to be loyal to Iggy," he said.

The 24-year-old rapper has also recently posted a photo of her on the set of "Fast and Furious 7" with co-star Michelle Rodriguez. She captioned the photo "#Fun."

The "Fancy" singer is now being compared to Brit artist Rita Ora who also had a cameo role in "Fast and Furious 6." Ora has also appeared on Azalea's new single "Black Widow."

According to Daily Mail UK:

"The two beauties may have been sharing tips on the set of the cinematic video clip to their new track, which has been shooting in downtown LA recently."

"It has already been a massive year for Iggy, who had her first No.1 in the US with her track Fancy with Charli XCX, off her debut album The New Classic. She was also announced as the host of MTV series House Of Style, which will begin filming later this year."
