Gwyneth Paltrow will sing live at the Country Music Association Awards (CMAs) next month.

The actress - who is married to Coldplay singer Chris Martin - will be joined on stage by Vince Gill to sing the title track from her new film 'Country Strong'.

Oscar winner Gwyneth plays a fallen country singer, who tries to resurrect her career through touring in the film, and director Shana Feste insists the actress put a huge amount of effort into her vocal performance in the movie.

Shana told People.com: "She worked very hard on the music. She had guitar lessons and vocal lessons and she took it very, very seriously.

"I just knew that she had the chops to do it and I thought that it was a surprising choice.

"She's not who you'd think of when you think country singer. Your mind doesn't immediately go to Gwyneth Paltrow, but I knew that she had the acting ability to pull it off."

The actress has previously revealed how she researched her role by looking at the history behind some of country music's legendary figures.

She said: "I sort of started at the beginning with Hank Williams Sr. and Johnny Cash and really studied Dolly Parton and Loretta Lynn.

"I had never really known very much about country music, and I now am very into it. I know a lot more about it than I did."

Gwyneth, 38, showcased her vocals in 2000 film 'Duets', and has also recently signed up to guest star in TV show 'Glee' in which she is set to perform three or four solo songs.

The Country Music Awards will take place in Nashville on November 10, while 'Country Strong' is released in the US on 22 December and elsewhere on 7 January.
