'How I Met Your Mother' Season 8 Promo: Barney And Quinn Talk Wedding Details (VIDEO)

The "How I Met Your Mother" premiere is still three weeks away, but we have a new trailer to tide you over.

While Season 7 of the CBS series left off with a surprising flash forward to Barney (Neil Patrick Harris) and Robin's (Colbie Smulders)' wedding, the Season 8 teaser (above) has Barney dealing with his upcoming marriage to Quinn, played by Becki Newton.

"Barney Stinson is absolutely, 100 percent going through with this wedding!" Ted (Josh Radnor) says when Barney starts getting cold feet.

Lily (Alyson Hannigan) manages to shake things up by saying, "I almost just blurted out that Barney used to date Robin!" which Quinn overhears.

But Barney's love life isn't the only big storyline this season. The return of Victoria (Ashley Williams), Ted's girlfriend from Season 1, will bring new elements to the show's upcoming Season 8. And Radnor couldn't be more excited to be working with Williams again.

"I love working with Ashley," Radnor told The Huffington Post in May. "She came back for that episode earlier this year, and it was super fun. [The writers] wanted to bring her back after seeing us together again -- they just love that. So they brought her back, and we had such a fun time. And it looks like she'll be back at the beginning of next season!"

"How I Met Your Mother" premieres on Mon., Sept. 24 at 8 p.m. ET on CBS.
