Backstreet Boys Resume Tour

Aug. 24 -- Teenage fans will get their chance to see the Backstreet Boys tonight when the boy band resumes its delayed Black & Blue tour in Wisconsin.

The girls have an extra reason to scream, shout and throw their arms in the air at the Milwaukee gig as it marks singer A.J. McLean's first appearance with the group since he entered rehab in July.

McLean sought treatment for alcohol abuse and depression. He is expected to continue his treatment while on tour.

Brian Littrell says the break was good for all five members of the group. "I think the emotional health of the group is really on the up and up," Littrell told the Los Angeles Times. "A.J. is doing fine."

The delay means a new opening act. Shaggy had planned on filling the slot but dropped out when the schedule changed. He is replaced by Sisqo.

Madonna on HBO
