Thank You singer Dido has been working on a new album and has been teaming up with some big names in the studio.

The 40-year-old singer is back in the studio laying down tracks for her fourth record and set to collaborate with some big names in the industry.

A source told the Daily Mail newspaper: "She's writing again and is in the studio recording some fantastic material. She has a fantastic team behind her and there will be at least two surprise duets on the album.''

As well as working on her career, last year, the singer, whose album No Angel sold 21 million copies worldwide, became a mother for the first time, giving birth to son Stanley in July.

However, her pregnancy meant she missed out on the opportunity to perform her song If I Rise, from the movie 127 Hours at February's Oscars.

She wrote on her website at the time: ''Hello everyone, It's been a month of amazing news for me and now I have some more to share. Me and my husband Rohan are expecting a baby and we're beyond happy and excited about it.

''So as some of you already know, I won't be able to travel to Los Angeles for the Oscars ceremony to perform If I Rise.

''Obviously I'm really gutted about not being there - going to the Oscars has literally been a dream of mine since I was about nine.''
