Taylor Swift has praised Pharrell Williams as a ''sorcerer of happiness''.

The 'Shake It Off' hitmaker is a key adviser to the contestants on the new series of 'The Voice' US and while her old friend Blake Shelton likes to make her feel ''uncomfortable'', the 'Happy' singer left her feeling ''really good'' when she worked with his team.

She said: ''The first person that I worked with was Blake Shelton, who I've known for years because we both have been in the country music scene for years and years and years

''His favourite this to do is to make me uncomfortable!

''And after you talk to Pharrell, you feel really good for about two weeks straight... he's like a sorcerer, of happiness.''

Taylor and Pharrell hit it off so well, they are now planning to get together in the recording studio.

She told 'Access Hollywood': ''Pharrell and I were talking, in the breaks yesterday, and we just kept saying, 'We have to do something together!' He's like, 'You just call me. Call me when you figure it out.'

''I'm like, 'You call me if you figure it out first!' ''

And the 24-year-old beauty can't wait to work with No Doubt star Gwen Stefani and her team on the show.

She gushed: ''I look up to her so much because she's continued to do her thing. I love that she never veered away from red lipstick, I can relate. I'm really excited to spend time with her.''

As part of her position as key adviser - a role which Chris Martin undertook last series - Taylor will also work with fourth coach Adam Levine and his team.
