Taylor Swift has ''no complaints'' about starring in 'Cats'.

The 30-year-old singer appears as feline character Bombalurina in the CGI-heavy big screen adaptation of the much-loved stage musical which has been mauled by critics and been a major box office flop.

But Taylor has defended the film insisting she loved shooting the project as it gave her the opportunity to work with composer Andrew Lloyd Webber - who adapted the 1939 poetry collection 'Old Possum's Book of Practical Cats' by T. S. Eliot into the 1981 show -

Speaking to Variety, Taylor - who was nominated along with the 71-year-old writer for the Golden Globe for Best Original Song for their track 'Beautiful Ghosts' from the film - said: ''I'm happy to be here, happy to be nominated, and I had a really great time working on that weird-ass movie.''

The 'Lover' hitmaker and Andrew is now her ''buddy'' since they worked together which, for her, means the entire 'Cats' experience was completely worth it.

She added: ''I'm not gonna retroactively decide that it wasn't the best experience. I never would have met Andrew Lloyd Webber or gotten to see how he works, and now he's my buddy. I got to work with the sickest dancers and performers. No complaints.''

Taylor's co-star Jason Derulo - who plays Rum Tum Tugger - has also publicly defended the movie, insisting Tom Hopper's project is unique and has defied ''all rules''.

The musician said: ''Any time you defy what an art form is, any time you defy all rules, there's going to be some push-back, obviously.

''But it's an incredible piece of art done by some of the best people in the world.

''I am just excited for the people to actually see it because reviewers, I mean, what the hell do they know? Have they made a film ever in their life?''

Derulo compared the negative reaction to the film from critics to the way people responded to the original stage show which has been running around in theatres around the world for the past four decades.

He said: ''Reviews don't matter, man. At the end of the day, people are gonna go see it and it's gonna be a deportation into another dimension.

''It's an incredible, incredible, brave piece of art. It has always been that way. When it came out on Broadway, people were like, 'What is this?' It's something totally different.''
