The cast of 'Chicago' will reunite at the Oscars later this month.

Stars Renee Zellweger, Catherine Zeta-Jones, Queen Latifah and Richard Gere are to come together at the Dolby Theatre in Hollywood for the Academy Awards on February 24 - a decade after the film won Best Picture at the 2003 ceremony - and producers of the film and ceremony Craig Zadan and Neil Meron feel their appearance will be very ''appropriate'' for the evening.

Neil said: ''In a night of celebration of the music of the movies, we find it very appropriate.''

Craig added: ''We can't talk about what they're going to do!''

The duo have also promised a ''staggering'' amount of performers and have realised there aren't enough dressing rooms to cater to all the guests.

Neil continued: ''I don't think any Oscars have been as performance-based. When you do an Oscar show, you don't have a dressing room problem. The presenters don't get dressing rooms. And how many people perform on the Oscars, like one or two?

''We have a staggering amount of performers, and each of them needs a dressing room .. We're measuring the magnitude of how big the show is by the fact that we don't have [enough] dressing rooms.''

Stars who are already confirmed to share their talent at the event include Barbara Streisand and singer/songwriters Adele and Norah Jones - who will sing their Oscar-nominated tracks 'Skyfall' and 'Everybody Needs a Best Friend'.

Host Seth Macfarlane will also share his singing voice for the audience and the producers are confident the funnyman will do a ''great'' job on the night.

Neil said: ''He's going to be very present as a host, as a host should. Seth really does understand and have great reverence for the music of the movies. He loves it.''
