TV Article 'Michael Forever': Christina Aguilera, Beyonce, Cee Lo Green, and Michael Jackson's children appear at controversial tribute show By Clark Collis Clark Collis Senior Writer EW's editorial guidelines Published on October 8, 2011 10:48PM EDT Photo: Samir Hussein/WireImage/Getty Images Christina Aguilera, Cee Lo Green, and Ne-Yo all performed at the controversy-plagued Michael Jackson tribute concert “Michael Forever” earlier today, according to the AP. Jackson’s three children — Paris, 13, Prince, 14, and Michael Joseph Jr., 9 — also appeared onstage to address the audience at the show, which took place in Cardiff, Wales. Ne-Yo started the concert with a performance of “Billie Jean;” Jackson’s brothers Marlon, Tito, and Jackie tackled the Jackson 5 hit “Blame It On the Boogie” with British boy band JLS; and Christina Aguilera sang “Smile.” Meanwhile, Beyonce performed “I Wanna Be Where You Are” via satellite. The Jackson children returned to the stage for the finale, “Don’t Stop ‘Til You Get Enough.” “Michael Forever” had attracted criticism for a variety of reasons, including the fact that it was set to coincide with the manslaughter trial of Dr. Conrad Murray, who is accused of contributing to Jackson’s death. Several of Jackson’s other siblings, including Janet, declined to take part in the concert and last week the Black Eyed Peas withdrew from the show, citing “unavoidable circumstances.” Read more: Troubled Michael Jackson tribute concert hits new snag with Kiss’s Gene Simmons Jay-Z says wife Beyonce is ‘the second coming’ of Michael Jackson: Yes, he knows it’s blasphemy Another year, another King of Pop tribute in jeopardy: Michael Jackson’s estate, brothers won’t support latest effort
