Taylor Swift's Diet Coke commercial could be hailed as the cutest advertisement ever. The "Shake It Off" singer shared the video clip with her Twitter followers, and it got tons of likes in just a matter of minutes. In addition to the super cute video, fans were also treated to a sneak peek into the pop star's latest single.

The 24-year-old singer showed off her new commercial for Diet Coke, teasing her fans with a brand new song grabbed from latest album, 1989. The track sounds great, and fans just cannot wait to hear the whole song.

The commercial kicks off with the beautiful Taylor Swift sitting comfortably on her coach, sipping on her Diet Coke, and playing with her ultimately adorable kitten. Every single time she takes a sip, the cats multiply.

As the video nears its end, Swift is shown surrounded by hundreds of kittens, with her voice singing a track that has not been heard before. The catchy beat of the song paired with the kitten-focused video was a fun sight to watch.

The lyrics are "And that's how it works / That's how you get the girl, girl." Fans can already tell that this track will be one of the crowd favorites from her latest album.

Moreover, it looks like Taylor Swift has been pretty busy of late. With this new Diet Coke commercial making its rounds and the new album, she also has some issues regarding another one of her singles, "Out of the Woods."

Rumor has it that "Out of the Woods" was actually a song that Taylor Swift wrote about her ex-boyfriend Harry Styles. Now, everybody is dying to know how the amazingly handsome One Direction member feels about the song being entirely about him.

A source told HollywoodLife.com, "This new song has put Harry in an awkward position because he's being forced to defend her! All his friends are making fun of Taylor over this, calling her names like 'Bunny Boiler' and 'Cray Tay'."

The source then added, "Harry doesn't want to be mean to her. He genuinely feels bad that he hurt her. So, now, he's stuck defending her. It's just awkward."
