9-1-1: Nashville hasn't even premiered yet, but fans are already hoping there are crossovers being filmed with the OG series. Oliver Stark fueled rumors that 9-1-1 and 9-1-1: Nashville will be filming together sooner rather than later when he shared an Instagram post on Sunday, August 3, writing, "6 Nashville Miles for breakfast." The social media upload included a video of Stark, 34, running in the city and he added a smirking devil emoji as well. Both ABC shows are currently filming as viewers await the premiere of the highly anticipated spinoff.
