Looks like newly-minted pop star Taylor Swift and Rock and Roll Hall of Famer Joni Mitchell won't be hanging around with each other on a movie set. Nor will they be belting out a rousing duet of "Big Yellow Taxi" on stage at an awards show. That's because Mitchell said no to Swift.

Here's how the story goes:

Back in April 2012, it was reported that Swift was in line to star in Sony's adaptation of "Girls Like Us," a book about the life and times of singers Joni Mitchell, Carly Simon and Carole King. But Mitchell herself shot down those rumors Sunday.

In October of that same year, Swift admitted that she was still eager to play Mitchell, but the role hadn't been confirmed yet. Now Mitchell candidly details how she prevented Swift from starring in the movie and how she completely stopped the project in its tracks.

"I squelched that," Mitchell recently told The Sunday Times of the scuttled biopic. "I said to the producer, 'All you've got is a girl with high cheekbones.' It's just a lot of gossip, you don't have the great scenes."

Mitchell also said of the book written by Sheila Weller, "It's just a lot of gossip, you don't have the great scenes. There's a lot of nonsense about me in books, assumptions, assumptions, assumptions."

Swift wasn't the only one tagged to co-star in "Girls Like Us." Alison Pill, "The Newsroom" actress, was in talks to play Carole King in before Mitchell blocked the film's production, according to Rolling Stone. John Sayles was hired as screenwriter with Kate Jacobs directing the movie. 

Had Swift landed the role of Mitchell in 2012, it would not have been her first acting stint. Her first acting came in a 2000 episode of "CSI: Crime Scene Investigation" and she made her big screen debut in "Valentine's Day" in 2010.

Putting the lost role of "Girls Like Us" behind her, Swift voiced the role of Audrey in the animated feature "The Lorax" in 2012. In addition, the "Shake It Off" singer contributed two original songs to "The Hunger Games" 2012 soundtrack: "Safe & Sound featuring The Civil Wars" and "Eyes Open." And earlier this year she had an on-screen role in "The Giver," according to CBS News.
