Kim Kardashian introduced a new feud as she debuted a project in which she battles it out with none other than Jimmy Fallon, and fans are officially picking sides.

Kardashian shared a new video to her Instagram that showed Fallon entering the office for Beats headphones, with the TV host excitedly saying, “I’ve always wanted my own signature Beats, and today it’s finally happening.”

Unfortunately, his happy mood was interrupted when he overheard employees comparing his Beats with those of Kardashian while they watched their two ads. Everyone seemed to favor Kardashian’s designs, saying, “We can only choose one set of headphones.”

Fallon tried to plead his case, only to be surprised by Kardashian being in the office. This led to the two facing off. Fallon said, “May the best person win,” and Kardashian replied, “Thank you, I will.”

Fans loved the fun video and quickly picked whether they liked Kardashian’s or Fallon’s Beats better. In the clip, Fallon’s headphones were a mustard yellow color, while Kardashian’s were different shades of brown and tan.

One fan replied, “I like Jimmy’s button >>>>>>>,” with over 800 people liking the comment, while a comment from the official Beats account saying, “🤎🤎🤎,” had over 650 likes, and counting.

“I love them both…but it’s Kim for me 😍,” said another, while someone else said, “Poor Jimmy! Lol the yellow just needs a rebrand 🌻.”

Others simply shared appreciation for the innovative ad, with responses like, “This ad is fireeeeeeee❤️😂,” “Kimberly is a marketing genius 🙌🔥,” and “The duo we didn’t know we needed🔥🔥🔥.”
