USA hit show "Psych" has announced that its current season, it's eighth, will be it's last. For spoilers for the series finale, and the reasoning behind ending the show, read on.

Actor James Roday recently sat down for an interview with TV Guide, where he discussed why they have decided to end the show.

"I think there's a lot of love and a lot of history and a lot of goodwill between Psych and the USA Network, and it was one of those things where they were 99.9 percent sure we were finished, but nobody actually wanted to push the button. Nobody actually wanted to let go because once you make the press release, once you put it out there that the show is ending, the show is ending," the actor said.

Star Dule Hill also shed some light on the reasoning behind ending the season while speaking with TV Guide.

"Our last two seasons especially have been getting stronger and stronger, and I feel like we're ending the show at the top and not seeing a decline in what we were doing," he said.

Roday also provided some spoilers for tonight's series finale.

"The series finale, I think, is probably the most emotional episode that we've had just because the heart of the show is, and always has been, two best friends who go on these crazy adventures and are willing to essentially die for one another doing it," he said.

Catch the series finale tonight at 9/8c on USA.
