Adam Levine has branded TV show Here Comes Honey Boo Boo as the "worst thing that's ever happened" to civilization. The Maroon 5 frontman has slammed the reality series - which follows seven-year-old beauty pageant contestant Alana Thompson and her family - for causing "decay" to society and insists its high viewing figures do not mean it has anything important to offer.

"Seriously, Honey Boo Boo is the decay of Western civilisation. Just because so many people watch the show doesn't mean it's good. So many people witness atrocities and can't take their eyes away from them, but that doesn't mean they're good. That show is literally The. Worst. Thing. That's. Ever. Happened!"

The Voice coach also slammed the "despicable" parenting shown in the program during his expletive-filled rant. He added to the new issue of GQ magazine, "It's complete f***ing ignorance and the most despicable way to treat your kids. F**k those people. You can put that in the magazine: F**k those idiots. They're just the worst. Sorry, I'm so sensitive to that - like, I don't know, man, it's upsetting. Just to clarify, I said, 'F**K THOSE PEOPLE.'"
