Justin Bieber found out Seth Rogen doesn’t like him, and he seems bummed about it.

Earlier this week, Rogen spoke to Howard Stern on Sirius and reminisced about the first time he met the Biebs. They were at a German talk show, and someone told Rogen that Bieber was a fan and wanted to meet him. But when the two had their meeting, Bieber didn’t exactly show his excitement. “I was like, ‘He’s a little bit of a motherf—er. Whatever. He’s a bit of a d—,'” Rogen told Stern.

That wasn’t the end of it though: Rogen went on The Today Show Wednesday to promote Neighbors and Matt Lauer asked him about the “feud.” “I would never say anything about it again if no one asked me,” Rogen laughed. “To me, the idea that a grown man doesn’t like Justin Bieber is not a controversial thought, like, why would I? It would be much weirder if I did like Justin Bieber, to me.” Fair enough.

Skip to 2:45 to see Rogen’s Bieber comments:

Bieber responded Thursday morning on Twitter, claiming the reason for his unenthusiastic behavior when meeting Rogen was because he was “probably a bit shy and didn’t want to be over the top.” The tweet could have done without the sarcastic “sorry I didnt bow down when I asked 2 meet u” comment but, still. Appreciate the effort, Biebs.
