Michael Bublé broke his own Christmas collaboration rule for this music legend

Michael Buble broke his Christmas collaboration rule for Cher... and who can blame him? 

The Home hitmaker teamed up with the Believe legend for a new version of his 2005 single on her new festive collection and recently admitted his usual stance is to reject any offers to duet at this time of year after becoming synonymous with the season following his 2011 album Christmas.

He's quoted by the Daily Star newspaper's Wired column as saying, "Every late September/October every artist, the ones that you know, the biggest artists in the world, start to call me and say, 'I have an idea, you and me should make a Christmas...'

"And I go, [mimics putting phone down] 'click', I say, 'Thank you so much, I know you're gonna kill it.'

"I made one Christmas record, 12 years ago! One!"

However, he had to make an exception when the pop icon got in touch. "That changes when Cher calls. Number one, when Cher calls, you pick up.

"And number two, she said that she wanted to cover Home, I wrote that song a long time ago and I am still so proud of it."

Buble noted he's worked with "everyone from [Justin] Bieber to [Barbra] Streisand, to Celine Dion, to Ariana Grande, to Lady Gaga", but insisted Cher - whose new album Christmas came out in October' - is "one of the greatest vocalists of our time", making it an easy decision.

Buble also teased that he can be a bit of a Scrooge over the festive season.

He joked, "When [fans] meet me and ask for a selfie or something I usually ask for $5 and they get disappointed and I'll never understand it.

"For the holidays, from late October to early January it's $10, the prices have gone up."
