seth rogen justin bieber watch what happens live gi Seth Rogen blasts Justin Bieber on 'Watch What Happens Live'

If anything was learned by Seth Rogen’s appearance on “Watch What Happens Live” Wednesday (March 12), it’s what he should become a regular fixture on the show. He talked about everything from his fellow Hollywood stoners to Kanye West and Kim Kardashian’s reaction to the “Bound 3” music video he did with James Franco.
Joined by “Neighbors” co-star Dave Franco, they also rolled joints with Andy Cohen and recreated a scene from “Twilight.” It really was an interesting night.
Still, the biggest moment came when Cohen asked Rogen about his thoughts on Justin Bieber. Back in January, Rogen tweeted some unkind words about the pop star, who is having a bit of an image problem these days. “Justin Bieber is a piece of s***,” he tells Cohen. “He’s obnoxious, he’s ungrateful, he’s insincere.” What’s worse, Rogen explains, “He puts people’s lives in danger.”
Chances are the pop star won’t be too happy about the diss, but when is he ever in a good mood anymore? Perhaps that “Twilight” recreation they did will help. Take a look at it below.
