Taylor Swift's first ever Diet Coke ad premieres during tonight's American Idol, but lucky for us, the singer just tweeted a link to the "Music that Moves" clip on YouTube.
The commercial, which she filmed in Nashville, features Taylor writing the lyrics to "22" in a notebook as she sits in her bedroom, visits a diner, and then preps backstage for a concert.
"I write on whatever I can find," she recently told Entertainment Tonight. "I write wherever I am, whenever I get an idea, in the middle of the day in the middle of the night -- and I like that the commercial just really showcased that." There's also some pretty funny footage of people singing along to the hit song -- which we've all done before!
Watch the commercial below, and then head over to ELLE.com to check out two exclusive images of Taylor behind-the-scenes on her shoot!
