Sophie Ellis Bextor's next single will be entitled 'Bittersweet'.

The 'Murder on the Dancefloor' singer - who took time out from the music scene to have her second baby Kit with The Feeling guitarist Richard Jones - will release the song in April after teaming up with producers Freemasons.

Writing on her twitter page, 30-year-old Sophie said: "the new single is called Bittersweet. it's written with those lovely Freemasons's again (sic)"

The song will also be written with pop music maestros Richard 'Biff' Stannard and Hannah Robinson.

She added: "the new single's about when you can't resist something that you know is bad for you. a guilty pleasure. Like watching 'Celebrity Big Brother' (sic)."

Earlier this month, Sophie revealed the video for the new single will be shot in the Russian capital, Moscow.

Her next album, which follows on from 2007's 'Trip The Light Fantastic', will feature collaborations with 'Can't Get You Outta My Head' songwriter Cathy Dennis and 'I'm Not Alone' hitmaker Calvin Harris.

Speaking to her fans on her official website, she said: "It's been a lovely experience to make this album and I am so looking forward to sharing it with you."
