Fergie was "thrilled" to record the theme song for 'Sex and the City: The Movie’.
The Black Eyed Peas singer - who forged a successful solo career with her debut album 'The Dutchess’ - said singing 'Labels and Love’ for the film adaptation of the US TV show was an honour.
She said: "I was thrilled to do this song. I’ve been such a huge fan for so long. My mother and I would watch it religiously. The song completely fits the personalities of the girls - it’s kind of a love triangle between love, friends and fashion."
Fergie - who is engaged to 'Las Vegas’ star Josh Duhamel - refused to confirm rumours one of the main characters dies in the film, due to hit cinemas worldwide at the end of May.
She added to America’s OK! magazine: "I saw the movie! But I can’t say anything about it!"
'Sex and the City: The Movie’ sees Sarah Jessica Parker, Kim Cattrall, Cynthia Nixon and Kristin Davis reunited for the first time since the show ended in 2004.
The film soundtrack is released in the US on May 27.
