EXCLUSIVE: A-List Star Kyle West Punches a Paparazzo in Dramatic 'The Arrangement' Sneak Peek

Uh-oh, Kyle West may be in trouble.

On Sunday’s episode of The Arrangement, rising Hollywood star Kyle West (Josh Henderson) finds himself in hot water after he lets his emotions take over, instead of his brain.

ET exclusively debuts a sneak peek from the episode, which kicks off with Kyle arguing with aspiring actress -- and his contractual girlfriend -- Megan Morrison (Christine Evangelista) after he discovers her in a compromising position in a dark back alley in Venice, Italy.

“What the hell were you thinking leaving the hotel like that?” an annoyed Kyle asks Megan.

“I was on my way to the gym and I ran into some friends and they invited me out,” Megan explains, her answer angering Kyle even more as he berates her about her new life in the spotlight.

In the middle of their very public argument, a paparazzo spots them and starts snapping away. But Kyle, whose patience is wearing thin, does something that will have ramifications later on.

“Not now, OK?” Kyle tells the pap, who ignores his request. “I said not now! Goddammit, I told you to stop!” And before you know it, Kyle punches the paparazzo square in the face, knocking the man nearly unconscious.

“Sh*t,” Kyle says with instant regret, before calling up reinforcements, aka his best friend and mysterious head of the Institute for the Higher Mind Terence Anderson (Michael Vartan). “I need you.” Smells like trouble!

The Arrangement airs Sundays at 10 p.m. ET/PT on E!.
