Yes, you may feel like you've climbed Mount Everest to get to Thursday, and the concept of Friday may feel like a whole other mountain range! If you need a quick chug of Gatorade (yes, I overstated that metaphor, and yes, it's obvious I know nothing about mountain climbing or literally any other form of exercise) to get through today, see Chrissy Teigen's Instagram account (opens in a new tab) No need; more specifically, enjoy this fun video of Miles Stevens singing along to the upcoming John Legend single "I Do":

Legend explains a little more about the single on Twitter: with Charlie Puth It's a collaboration with Charlie Puth and it won't be long before it's released. He tweeted, "I made this chorus so Miles could pronounce it better, @charlieputh." #IDo coming soon..."

What was Luna doing while Miles was working on the vocals? On his Instagram Story, Teigen released a video of Luna and Miles dancing to the song, and Luna seized the opportunity to perform her own rendition.

Meanwhile, Luna's favorite non-musical pastime is following her mother literally everywhere. Teigen posted a photo of herself trying to work on her laptop with Luna's head under her robe. She captioned the photo, " If you're thinking of having kids, great! But know that you will never be able to do anything alone again." Enjoy:
