While Paul Rudd was seen fangirling over musical guests One Direction before and during his stint as the host of 'SNL' this week, the tables were turned by 1D's Niall Horan.

The 1Der fangirled over Rudd and his 'Anchorman 2' co-stars Will Ferrell and David Koechner after the episode.

OK, so maybe he wasn't screming, but he did share photos of himself with the actors.

It was only fitting, since 1D crashed Rudd's opening monologue, which resulted in boy band vs. man band.

Horan captioned his snap with Ferrell, writing: "Here he is! The one and only! Will Ferrell!"

He was equally stoked about his time with Rudd, posting: "What a super great guy! Pleasure to work with! honour to meet! will never forget tonight!" How sweet, right?

Horan also posed with David Koechner, who plays Champ Kind in 'Anchorman.' We're left to wonder, though. Why no pic with Steve Carell, who plays Brick Tamland? It was Carell-as-Brick who told 1D to grow a pair during the monologue battle. Maybe Niall thinks Steve hates One Direction, too.

Or maybe not.
