The '22' star was amused at a comment from the 'I Kissed A Girl' singer on the social networking site.
Taylor Swift took to her Twitter account last night (22nd May) to plead with Katy Perry to "never change" following a play on words of one of her own songs.
The 'Firework' singer changed the lyrics of 'I Knew You Were Trouble' to inform her fans of her dinner plans – something which the country star loved.
"I knew you were truffle when you walked in #dinnertime," read Katy's post.
"@katyperry please never change," replied Taylor after retweeting the remark.
Meanwhile, Taylor was recently seen picking up eight prizes at last weekend's Billboard Music Awards 2013.
The star took to the stage to collect her Top Artist prize and thanked her fans for being the "longest and best relationship" of her life.
