Judges will.i.am, Sir Tom Jones, Anne-Marie and Olly Murs will be getting help from some of music's biggest stars when it comes to advising their hopefuls on this year's show as, following months of secret negotiations, producers were delighted to bring in a string of famous faces to offer guidance.

A source said: "Everyone is so excited to have such big names taking part in the new series.

"David Guetta is one of the hottest names in music."

The trio filmed their appearances before Christmas and contestants were "thrilled" to see their big-name mentors.

The insider added to the Daily Star Sunday newspaper: "'The Voice' is going from strength to strength.

"Now 'X Factor' has gone, the producers are able to get even better names. The contestants were thrilled that they got to be mentored by such accomplished artists."

Show bosses are also said to be in talks with other big name acts to perform on the live shows when the series returns to ITV later this year.

Anne-Marie previously vowed to mentor the winning act once again.

She said: "It feels so good to be back! I had the most amazing time last series, and I am so excited to be returning to my big red chair. "Winning with Craig last series was a special moment and I am determined to keep a hold of my crown!”

However, Olly has fired a warning shot to his rival coach, and insisted he's coming for the crown.

He added: "I cannot wait to be reunited with 'The Voice UK' family! We always have so much fun making the show and I’m sure this series will be no exception.

"Anne-Marie needs to watch out because this series I’m taking back the title!”
