Nick Carter's Sis Dead at 25

A prescription drug addiction is suspected in the sudden death of 25-year-old Leslie Carter, the singing sis of Aaron and Backstreet Boy Nick Carter, reports TMZ. Carter, mom of a 10-month-old baby girl, was found dead in an upstate New York home this week. The singer had moved from Canada to New York to live with family members as she tried to kick her addiction, sources told TMZ. She was left alone in the home for a short time, but relatives returned to find her unconscious.

The family is "deeply saddened" by Leslie's death, said a statement. Nick Carter said he doesn't plan to cancel upcoming appearances because of the tragedy. "Performing is cathartic to me and I am dedicating the rest of my tour to my sister since she loved to watch me perform," the singer said in a statement. Leslie Carter's single "Like Wow" was featured on the 2001 Shrek soundtrack. Her 1999 debut CD with Dreamworks Records was never released. She leaves behind husband Mike Ashton and their baby, Alyssa. (More Leslie Carter stories.)
