Taylor Swift steals a fellow musician's cookie dough treat and beats up comedian Andy Samberg in a quirky new AT&T commercial.

The singer is followed around a studio complex by a camera as an annoying narrator describes her every thought and move, which includes playing with her cat Olivia, checking out pictures of dolphins and sea creatures online, and eating spilled food off her clothing.

She ends up back in front of the microphone after kicking Samberg through a wall during a corridor fight and crawling through a ceiling air shaft after becoming locked in a closet while hiding from the guy whose cookie dough she ate.

The hilarious new commercial for Taylor Swift NOW, a curated video catalog for AT&T cellular customers, debuted online on Thursday (07Sep17).
