Although it hasn't been officially confirmed whether Adele has recorded the theme for the brand new James Bond movie or not, One Republic's frontman claims to have heard it and has praised it as the "best Bond song".

Ryan Tedder posted a tweet about Adele's supposed 'Skyfall' theme and although it was subsequently deleted from the web, MI6-hq.com reported that it said:

"I've heard it. Best Bond song in my lifetime. Hands down- hats off once again to Paul Epworth and Adele. hope they win Oscar!"

The same site explained that Adele's publicist, Paul Moss, also revealed his excitement on the social networking site, writing: "Are you ready for the SkyFall Theme song? Hope you are because it's coming and it's going to explode."

'Skyfall' will hit cinemas on October 23 and it's thought that the official theme song might be unveiled on global James Bond day, which falls on October 5 this year.
