The 38-year-old actress took to the stage armed with a guitar at the CMA Awards to sing Country Strong, which is also the title of her forthcoming film, but first got advice off some superstar friends.
She told Access Hollywood, 'I kind of asked my girl singer friends [for advice]. I asked Faith [Hill] a lot of questions... and Beyoncé actually too.'
'I studied Beyoncé a lot and her concerts for her kind of confidence,' she added. 'And I'm lucky that I know some singers in real life.'
Being married to Coldplay front-man Chris Martin probably helped her to perfect her performance too.
