Seth Rogen has said some really mean things about Justin Bieber in the past.
There was the time Rogen referred to Bieber as an obnoxious piece of... you know what.
In an interview with Andy Cohen last year, Rogen added that Bieber was "ungrateful and insincere."
There was also that time Rogen said he hates Bieber, who he called at "motherf-cker."
The actor uttered these insults back when Bieber was peeing in mop buckets, speeding around his neighborhood, throwing loud parties, hurling eggs at neighbors are acting like an entitled doofus.
So it was understandable.
And even Justin seemed to understand it, considering he pleaded for Rogen to roast him many months ago on Comedy Central.
Rogen didn't respond to those requests at the time, but he did appear this week on Ellen. Which happened to coincide with Justin Bieber Week on Ellen.
The artist will appear on that talk show every day this week, culminating in a small concert on Friday.
First, though, he had some unfinished business to take care of with Seth Rogen.
“It’s not really a beef. I just called him some really mean things on social media for no real reason,” Rogen told Ellen of his feud with Bieber, taking responsibility for it.
“It really hurt his feelings, as it should have, and a lot of people got really mad at me.”
Rogen went on to say he had only met Justin one time back when he made his negative comments, and the interaction actually went very well.
Moreover, the two met backstage prior to Rogen coming out to speak to Ellen and now they've made up and it's all good.
But it's not truly all good until we see the celebrities hug it out and settle the beef for ourselves, right?
