Backstreet Boys singer Nick Carter has led tributes after the death of his younger brother and fellow star Aaron.

In a social media post Nick, 42, said the pair had a “complicated relationship” but his love had “never ever faded” for Aaron, who was 34.

Nick’s band also dedicated a song to the younger Carter during a concert in London on Sunday evening.

Aaron’s body was found at his California home on Saturday. No cause of death has yet been disclosed.

A statement from the late singer’s team that day confirmed the news, promising more information when it was available.

US media reported that police found the lifeless body of the I Want Candy singer in the bath.

Carter, a former child star, sold millions of albums, having gained fame as an opening act for the Backstreet Boys in the late 1990s.

His brother Nick, a member of the American boy band, wrote online: “I will miss my brother more than anyone will ever know.”

His post acknowledged that their brotherhood had not been without its tensions, which culminated in the elder Carter taking out a restraining order against his sibling in 2019.

Alluding to Aaron’s well-documented struggles – which reportedly included multiple trips to rehab – Nick commented: “Addiction and mental illness are the real villains here”.
