Turning 50 has not dulled the glow emitted by Michigan native Madonna, who debuted her latest tour at the Meadowlands in Hackensack, N.J., critics said.

Age was no factor as the U.S.-turned-British resident sang and danced for nearly two hours Saturday night, the New York Daily News reported Sunday.

"Madonna lived up to her reputation as the queen of pop," the New York Post wrote, adding the "Sticky and Sweet" tour could be her best live effort to date.

Not one to shy from political controversy, Madonna included videos that had Republican U.S. presidential nominee John McCain alongside Nazi leader Adolf Hitler and Democratic presidential nominee Barack Obama with Mother Teresa.
