Such a Sweet Emotion! Taylor Swift has a ball performing with Aerosmith legend Steven Tyler as they rock Nashville 

When he was the king of rock she did not even have any Toys In The Attic.

But Taylor Swift still looked like she was having a great time performing with Aerosmith legend Steven Tyler in Nashville on Friday.

The dynamic duo looked like they were having a great time as they went through their paces while performing sappy ballad I Don't Want to Miss a Thing in front of a sold out audience.

The 67-year-old, who is releasing a country record next year, made for an unusual on-stage pairing for the svelte 25-year-old warbler, especially as she has turned her back on that very genre to perform pop.

Steven's appearance was rather apt though, as the saucy Shake It Off starlet is in the middle of her 1989 Tour, a year in which Aerosmith had firmly reestablished themselves after a fruitful comeback.

 Thankfully at his age, Steven does not have to worry about losing his credibility with rock fans, especially after his credibility-sapping stint on American Idol.

The former judge had previously joked how he would like to work as her intern. 

With a twinkle in his eye, he said: 'She's blonde with all the hits. Taylor Swift. She's hot.

'More than that, she's beyond talented. I have to write a song with her.'

It seems Taylor is quite a fan of the Eat The Rich star too, as she was hamming it up for the audience by gesticulating wildly throughout their duet.
