Taylor Swift has shared her "favourite" Grammys moment so far - spending time in her dressing room with Sir Elton John and Ed Sheeran.

The country songstress is currently in Los Angeles ahead of the prestigious annual music ceremony.

John and Sheeran are set to perform a duet together tonight (February 10).

Swift is enjoying the lead up to the show, and took to Twitter to share her experience so far with her fans: "Favorite Grammy day moment so far: sitting in my dressing room with Sir Elton, watching @EdSheeran play new songs on his guitar. (sic)."

Sheeran posted a photo of himself with John on the social networking site with the accompanying caption: "Preparing for a duet... (sic)."

He later added: "I be on my suit and tie shit (sic)," seemingly in reference to his smart outfit for the night ahead.

Sheeran also thanked fans for their "lovely tweets". Watch a recent interview with Ed Sheeran here:
