According to TMZ, McLean’s drinking was affecting rehearsals for the Backstreet Boys’ upcoming joint tour with New Kids on the Block. On Sunday, McLean wrote on his twitter,
“I love u all and wish me luck! I start my sober journey tomorrow!”
In 2001, the Backstreet Boys postponed their ‘Black & Blue’ world tour so McLean could enter treatment for alcohol abuse, depression and anxiety. He was reportedly six years sober in 2008.
