“At the moment his cause of death is being investigated. We ask that you give the family time and they will have more information when available.
“We cannot express the outpouring of love coming in.”

Carter got his start opening for the Backstreet Boys on a 1997 tour and later that year he released his self-titled debut album.
His second studio album, Aaron's Party (Come Get It), was released in 2000 and went triple platinum by the Recording Industry Association of America.
It featured the singles I Want Candy, Aaron's Party (Come Get It) and That's How I Beat Shaq, and he performed the album several concerts by the Backstreet Boys and for Britney Spears on the Oops! … I Did It Again tour.
He went on to release three more studio albums, 2001's Oh Aaron, 2002's Another Earthquake! and 2018's Love.
Carter also tried his hand at acting, guest-starring on shows including Lizzie McGuire and making his Broadway debut in 2001 as JoJo the Who in Seussical The Musical.
He made the move to rap music in recent years, throwing off his child star image with a number of face tattoos.
Carter also had his share of controversy as well as several run-ins with the law.
The singer had his first child Prince with Melanie Martin in 2021.
