The world was a dark dark place before Kanye West released his “Bound 2” music video featuring his topless fiancee and plenty of bouncing action. Then came Seth Rogen and James Franco’s parody of the music video and the world got even brighter. Now, actor Zac Efron has released “Bound 4.”

Efron posted a shirtless photo of himself and Rogen with the words “Bound 4” written in large letters. The following message accompanied the Instagram post: “Whether you’re a #KanyeWest fan or not, fans are#Bound2 get a kick out of this new still from #ZacEfronand #SethRogen’s film #NeighborsMovie Check out all the neighborly shenanigans when the comedy hits theaters next May! #uhhuhhoney.”

Earlier this week, Franco and Rogen took a short break from filming their new movie “The Interview” to shoot a parody of West’s “Bound 2” music video.

Known as “Bound 3,” the video starts with the following message: “While on the set of their movie, The Interview, James Franco & Seth Rogen felt inspired to recreate their favorite new video. Shot. For. Shot.”

After posting to Facebook on Monday, the actors invited Kimye to check it out: “Hey @KimKardashian & @kanyewest check out what me and @JamesFrancoTV did on the set of @TheInterview. #Bound3,” Rogen tweeted with Franco adding, “#bound3 #sethrogen #love — a little video Seth and I made in our down time.”

Given the goofiness of the parody, Kim could have reacted with a smile or disgust. It turns out that she thought it was hilarious. “Soooo funny,” she tweeted.

But Kim wasn’t the only high-profile fan of “Bound 3.” “Kanye says what’s up!” Kim tweeted. “He loves u guys! He laughed so hard at this.”

“That’s so awesome!! Ha!! Tell him what’s up back,” Rogen tweeted back to Kim. “So psyched you guys like it!”

The video features Franco doing his best Kanye impression and Rogen trying hard to look sexy.

“Some of those positions were really uncomfortable,” Seth told Kim via Twitter. “That s–t is harder than it looks.”
