Wedding bells are ringing on "How I Met Your Mother," but it looks like Ellie Kemper has changed her RSVP from a "yes" to a "no" for Robin and Barney's wedding. Enter Anna Camp.

According to TVLine, Kemper has bowed out of "How I Met Your Mother" due to a scheduling conflict and Camp will replace her as Cassie, one of the most "attractive, available and unfortunate" guests at the wedding.

"I think that Ted and Robin have a connection and they were in love with each other at one point, and that's something that doesn't just vanish," she said. "So I think it's dealing with that and walking that line. I don't think there's going to be any flip-flopping happening -- I've made my choice and I'm sticking with it, but it's hard when one of your best friends is someone that you've had romantic feelings for, who's also the best man. It creates a lot of drama, creates good TV!"

"How I Met Your Mother" Season 9 premieres on Monday, Sept. 23 at 8 p.m. ET on CBS.
