The "Adore You" singer recently posted a picture online of her swapping spit with the Victoria's Secret model.
"LOVE!!!!!We finally got the filmed developed Mush," Miley wrote as the photo's caption.
We can't even imagine what was going on the night the picture was taken! Maybe it was around Miley's birthday? This isn't the only time these two famous ladies have hung out. Last month they were spotted at a coffee shop in Amsterdam together.
Cara is known to hang out with other famous people too. She is really good friends with Taylor Swift and Rihanna as well.
What do you think about Miley's pic with Cara? What do you think Harry thinks about it?
