UPDATE: Police departments across the nation are challenging each other to lip sync battles.

The trend has now made its way to the Tennessee Valley.

Last week, officers with the Collegedale Police Department posted a video of two of their finest lip-syncing the iconic "Cops" theme song "Bad Boys."

Collegedale then challenged the Cleveland Police Department and the Signal Mountain Police Department. Both departments accepted.

The Signal Mountain Police Department posted a video of two of their sergeants lip syncing to Alice Cooper's "Prettiest Cop On The Block." Signal Mountain challenged the Chattanooga, Red Bank and Soddy-Daisy Police Departments.

Cleveland decided to get the public involved on Facebook to decide if they would film a video.

The people said yes, and the officers listened posting a lip sync video to "Havana" by Camila Cabello.

The Cleveland Police Department extended an invitation to the police departments in Chattanooga and Knoxville and the sheriff's departments in Hamilton and Polk Counties.

Several other Tennessee Valley departments, including Soddy-Daisy, have also participated:
