The on-camera hostility between Couples Therapy stars Doug Hutchison and Nik Richie has reached fever pitch on a number of occasions, but it still doesn't match up to the insane drama off-camera, Breaking Celebrity News is exclusively reporting!

As we previously reported, outspoken Richie, founder of the website The Dirty almost came to blows with 52-year-old Hutchison after branding him a "child molester" for marrying 16-year-old Courtney Stodden.

But that's far from the only barb Richie has thrown at the Green Mile star, and an on-set source tells Breaking Celebrity News exclusively that things got so bad between the two at one point that producers insisted they were both flanked by a bodyguard at all times!

"Nik and Doug absolutely despise each other," the source says. "It is certainly not all put on for the cameras, there's a real, genuine, complete loathing between these two.

"Nik is very good at articulating his disgust for Doug and puts him down at every single opportunity, he makes no effort to hide his disdain at Doug marrying Courtney and the child molester accusations that aired were just the tip of the iceberg!"

"From the moment Nik met Doug he told producers that he got a creepy gay vibe off of him, and Nik hasn't let up from that moment on — he's called him 'Michael Jackson creepy' and said he did not want Doug around his daughter when she came for an on-set visit.
