It’s fair to say that Ashley Benson (Hanna) is probably the funniest actress of all the Pretty Little Liars stars, and she’s regularly voiced her desire to play comedic roles in the future. So it’s great news that Ash will guest star on an upcoming episode of How I Met Your Mother.

CBS tweeted the news today (December 13): “#HIMYM CASTING NEWS!#PrettyLittleLiars@AshBenzo is going to guest star as Barney’s ???? on Jan. 21! Suit Up!”

No details yet on how her character will relate to or interact with Barney (Neil Patrick Harris), but we have a good feeling that this episode will be hilarious. And here’s a fun fact: Lucy Hale (Aria) guest-starred on HIMYM way back in Season 2!

Mark your calendars!

Catch the return of PLL Season 3 on Tuesday, January 8, 2013 at 8 p.m. ET/PT on ABC Family.
