British rapper Lady Sovereign is trying to convince pop star Gwen Stefani to take a different musical direction - into hip-hop. Sovereign - real name Louise Harman - is set to support The Sweet Escape singer on her upcoming (Sep07) UK tour, and hopes she'll be able to get Stefani to try her hand at rapping. The Random hitmaker says, "I like making people do music they wouldn't normally. "I would like to do something with Gwen, and do music she doesn't normally mess about with."
