The 36-year-old posed for the cover of the September issue of Treats! magazine, reports eonline.com.
"I've done some topless photo shoots before, but never completely nude," Thicke said.
"It was very sexy and I like that. At first I thought, 'Okay, let's just do topless' ... but, again, my wife and her friends were like, 'No way ... go all the way.' I think we definitely pushed the envelope," he added.
The singer was recently in news for sharing the stage for Miley Cyrus's raunchy performance at the MTV Video Music Awards.
