Adele has finally confirmed what has turned out to be the worst-kept secret since reports about her pregnancy first surfaced: The British singer is, indeed, the woman behind 'Skyfall,' the theme song of the forthcoming James Bond film of the same name. Adele, who wrote, produced and performed the track with producer Paul Epworth, erased all doubts about her involvement recently when she tweeted a picture (left) featuring the sheet music for the song.

Adele, who will premiere to song via her official website on Thursday (Oct. 4) at 7:07PM EST on the dot, admits she didn't immediately jump at the chance to join the Bond franchise. "I was a little hesitant at first to be involved with the theme song for ‘Skyfall.’ There’s a lot of instant spotlight and pressure when it comes to a Bond song," she says. "But I fell in love with the script and Paul had some great ideas for the track and it ended up being a bit of a no brainer to do it in the end."

"It was also a lot of fun writing to a brief, something I’ve never done which made it exciting," she adds. "When we recorded the strings, it was one of the proudest moments of my life. I’ll be back combing my hair when I’m 60 telling people I was a Bond girl back in the day I’m sure!”

'Skyfall' will be available to purchase via download immediately following Thursday's debut.
