British bands JLS and N-Dubz shared the limelight with U.S. star Beyonce after all three acts won two MOBO awards each. The ceremony celebrates black, urban music.

Two of Michael Jackson's siblings also appeared at the MOBO (Music Of Black Origin) prize ceremony in Glasgow last night (Sept. 30), held for the first time outside London this year.

The late singer's sister La Toya introduced a musical tribute to Jackson, who died of a prescription drug overdose on June 25, and his brother Jermaine performed.

Boy band JLS picked up prizes for best newcomer and best song ("Beat Again") in the public vote, while hip hop act N-Dubz won the best U.K. act and the best album category for "Uncle B."
