Jason Sudeikis and Olivia Wilde have been dating for about a year. Olivia, 28,  started dating the ‘Saturday Night Live’ comedian, 37,  shortly after her divorce from Tao Ruspoli was finalized in October 2011.

According to US Weekly, the couple moved in together this past fall, and were “totally inseparable.” Now, RadarOnline is reporting that the couple is planning a wedding in Sudeikis’ hometown of Kansas City, Kan.

“Everyone in town is buzzing about the wedding,” a source told Radar. “They have already booked the venue and are in the process of finalizing the rest of the details.”

While the Kansas nuptials may just be a rumor, the couple doesn’t seem shy about committment: While at a Glamour magazine event, Wilde recently revealed that she is “blissfully, hopefully, wildly in love.”

And there’s at least one area where their relationship doesn’t need any help.

“We have sex like Kenyan marathon runners,” Wilde added.

Reps for Wilde and Sudeikis have not yet responded to requests for comment.
