The singer was filmed by TikToker Douglas Anthony seemingly working the cash register at the store. The video, posted on Thursday, shows Timberlake in a gray jacket, blue shirt and beanie, nonchalantly scanning Anthony's items, which included a speaker, mints and gum.
"What else did you want?" Timberlake asks at one point, as he rings up the items.
"Justin Timberlake said post this for the naysayers," Anthony wrote on the clip, also adding, "HeSaidNoHateAndHeWillStartATikTok." Additionally, looking at the hashtags he used, it appears as if they were at a Target in Colorado.
