The Country star premiered the track during last night's star-studded event in LA.
Taylor Swift performed her new song 'Ronan' for the first time at the third annual Stand Up To Cancer Telethon in Los Angeles last night (8th September).
The track is expected to feature on the country singer's new album 'Red' which is released next month.
After the emotionally charged performance, Taylor could be seen trying to hold back tears, and was later pictured weeping as she left The Shrine Auditorium accompanied by her mother.
She wore a red floral dress and sat isolated in the middle of the stage with just her acoustic guitar player joining her for the tender rendition of the song.
The track is a tribute to a three year-old boy called Ronan - who passed away following a battle with neuroblastoma last year.
Taylor penned the lyrics after reading a blog post from the child's mother, who shares songwriting credits on the track.

Justin Timberlake, Twilight star Robert Pattinson and Gwyneth Paltrow were also among the other stars who took part in the charity event.
The track has been released on iTunes - with all proceeds going to charity.
Meanwhile, Taylor also performed her latest single 'We Are Never Ever Getting Back Together' for the first time at the MTV Video Music Awards 2012 last week.
