BEYONCE KNOWLES - KNOWLES PLANS MARTIN DUET

R+B beauty BEYONCE KNOWLES is calling on COLDPLAY frontman CHRIS MARTIN to collaborate with her in the studio.

The DESTINY'S CHILD star has worked with a host of urban singers in the past, including boyfriend JAY-Z, but she's determined to test her musical compatibility with rocker Martin to discover how their different pop styles mix.

She says, "I've done duets over the years, but would love to work with Coldplay. Singing with Chris would be cool."

Knowles' singing skills were in demand earlier this week (begs31JAN05) when ASHANTI announced her desire to team up with the CRAZY IN LOVE star to temper rumours of rivalry between them.
