Nick and Aaron Carter are grieving this morning after their sister, Leslie, passed away last night in upstate New York. Further details around the death weren't available.
The Carters told Access Hollywood, "Our family is grieving right now and it's a private matter. We are deeply saddened for the loss of our beloved sister, daughter, and granddaughter, Leslie Carter." The family requests utmost privacy "during this difficult time."
The 25-year-old singer married her husband in 2008 and gave birth to their daughter, Alyssa Jane Ashton, last April. Although she wasn't as famous as her brothers, Leslie pursued a music career in the '90s. Playing both the piano and clarinet, she signed on with DreamWorks Records in 1999, but the album was never released.
Our hearts go out to the Carter family during this difficult time.
