Beyonce Knowles' father and sister have teamed up to produce a new series of hip-hop baby toys. Mathew Knowles' Music World Entertainment has partnered with Planet Toys to launch Baby Jamz, the first ever hip-hop/rhythm inspired pre-school toy line - and new mum Solange Knowles will give the products a voice. Mathew Knowles admits Solange's son Juelz helped inspire the new line. He says, "Many children love music and dancing to hip-hop, so we have creatively combined great toys with the hip-hop versions of popular nursery rhymes. "My grandson, Juelz, was the inspiration for this idea and I am especially excited that most of the nursery rhymes are sung by my daughter, Solange."
