Taylor Swift has heaped praise on three of pop's leading ladies - Rihanna, Lady Gaga and Katy Perry.

The 'Red' star is due to face off against the superstar singers at the MTV EMAs on November 11 in Germany and Swift told Digital Spy that she has great admiration for them.

She is up against Gaga and Perry in the Best Female category for example but Swift doesn't have a bad word to say about the acts. The country-pop star said:

"I'm a fan of them as musicians and as people. I really like Lady Gaga and everything she is for her fans. I love Katy because she's really funny and makes me laugh at award shows and Rihanna is one of the friendliest people I've ever met."

Swift meanwhile opened up on how her hit single 'We Are Never Ever Getting Back Together' came about, adding that she wrote the song in 25 minutes. She said:

"I wrote it in the studio with Max Martin and Shellback and we were actually writing another song. Randomly this guy walked into the studio who I had never met before - but I heard of him through my ex - and he made some comment about how he'd heard that we were going to get back together. That was not the case! After he left I explained the story to Max and said, 'We are never ever getting back together' and someone said we should write that. I just grabbed the guitar and it just happened very randomly. It was hilarious - we wrote the song in 25 minutes."
