You may have seen this video being shared on social media, of a burly police officer giving his all while he lip-syncs Taylor Swift's big hit "Shake it Off."

Master Cpl. Jeff Davis of the Dover, Del., police department, is shown in his patrol car singing along, shaking his head and pointing his fingers while the song plays.

Since the video was posted on the department's Facebook page, Davis has become an Internet star.

The police department has gotten calls about the video from news media throughout the U.S. as well as several countries including England, Australia and Germany, the Associated Press reports.

It had nearly 11 million YouTube views by Sunday afternoon.

Davis is described as "the class clown" by department spokesman Cpt. Mark Hoffman, and said Davis knows the song well because his 10-year-old daughter is a fan.

He apparently has another fan, too – Taylor Swift herself:
