Taylor Swift & John Mayer Are Collaborating

Taylor Swift has had her dream come true - one of her musical idols John Mayer has written a new track especially for her to perform.

Swift first hinted that the pair would collaborate back in June, when she revealed both singers were keen to work together, and now it looks as though she got her wish.

"I was so excited when he Twitter-messaged me." Taylor explains. "He was like, 'Hey, I just wrote this song this morning and I can only hear you singing on it with me.' I was like, 'Yes!'"

Swift will be making her presenting debut this weekend on Saturday Night Live, and admits she is feeling nervous.

She also recently launched her own signature guitar.
