will.i.am praises 'fearless' Meghan Trainor

will.i.am loves working with "fearless" Meghan Trainor on \'The Voice\'.

The \'All About that Bass\' singer has joined the Black Eyed Peas star, Sir Tom Jones and Olly Murs on the judging panel of the talent contest in place of Jennifer Hudson and though Will admitted the idea of changing the line-up was "scary", he\'s enjoying the "refresh".

Asked his series highlight so far, he told heat magazine: "Meghan Trainor. She\'s super-sassy, super-talented, fearless, and has amazing depth, as far as her ability to write songs and produce. I like her a lot.

"It\'s nice to have a refresh but imagine going to The Shard and saying, \'Floors 30-40? We\'re going to take those out and replace them with this.\' You can\'t just take 10 floors out, the building\'s up.

"It\'s scary at first but when it works you\'re like, \'Yo\'.

"That was the fear with J-Hud leaving but that\'s why I love Meghan - she\'s fearless."

The 45-year-old star thinks the programme has found a good "balance" with its judging line-up.

He explained to heat magazine: "Olly Murs is really good and Tom is awesome.

"I used to be the only ball of energy and now Olly has this wild flair.

"I\'m quirky, but at the same time, very thoughtful, and Tom has this wisdom.

"The balance now is great I\'m not as much the clown of the show, like in past years.

"They don\'t have to depend on me any more for the comic relief."

Will is also a judge on spin-off show \'The Voice Kids\' and is equally happy on the panel with Pixie Lott and McFly\'s Danny Jones.

He said: "On \'The Voice Kids\' it\'s a hoot.

"I still bring the comedy with me and Danny and Pixie\'s in the clouds. I frickin\' love Pixie\'s energy."
