London-based station Kiss 100 has signed up two new DJs as part of a shakeup of its weekend schedule.

Mark Ronson - who has Dee-jayed at P Diddy's birthday bash - will host a two hour Saturday night hip hop show as part of a four-hour block together with Princess Superstar at 9pm.

The other new signing is Rishi Rich, producer for the likes of Britney Spears, Mary J Blige, Craig David and Mis-Teeq. Rich will host a new Friday night show with an ‘urban-desi’ sound, including R&B, hip-hop, dancehall and all sorts of street genres.

“The term ‘superstar DJ’ doesn’t do justice to the status of Kiss 100’s latest signings," said Programme Director Simon Long. “Mark Ronson is the DJ of choice for New York’s celebrity party circuit, while the biggest artists are queuing up to employ Rishi Rich’s talents. Listeners can expect two very different sounding shows from these chart-topping music heroes.???
