How I Met Your Mother continues to build its slate of guest stars for the upcoming final season.

The latest addition? Ellie Kemper, who just finished a run as receptionist Erin on NBC’s The Office.

Kemper, who is set to appear in one episode (for now), will guest as Cassie, a pretty – and available! – guest at Barney and Robin’s wedding. TVLine first reported the casting.

She joins previously announced guest star Sherri Shepherd, who will play a woman Marshall meets on an airplane, and returning guest star Wayne Brady, who plays Barney’s bro.

How I Met Your Mother, which begins its final season Sept. 23, will hold its first-ever Comic-Con panel this Saturday, moderated by some EW reporter named Sandra Gonzalez.
