The accompanying piece suggested Shelton's "drinking and womanizing... helped torpedo his 4-year marriage", while his so-called friends were reportedly "terrified he could end up dead at this rate".
Shelton has now filed suit against publishers at Bauer Media in Los Angeles County Superior Court in a bid to protect his reputation. He has denied all accusations, insisting he isn't in rehab and has no plans to seek any professional treatment, and is seeking at least $2 million (£1.25 million) in damages, according to TMZ.com.
