A photo posted Monday overlaid with the text "a mighty heart" shows off just how teddy-bear-like the little critter is.
Another from two weeks ago shows them cuddled up with the simple caption, "butch."
He also posed while holding Nugget and another mysterious (but adorable) dog up to his head three weeks ago, writing, "heads of hair."
Perry shared her own Nugget video on Instagram Sunday, hinting that the winner of her contest for the best "Chained to the Rhythm" lip sync video might get the chance to meet her dog along with her at the iHeartRadio Music Awards.
Perry has another dog named Butters, who's also something of an Instagram star. He made his social media debut when Perry announced her "new Prismatic World Tour mascot" in 2014, E! News reports, and gained the Internet's admiration when he pooped on his human's phone to get back at her for taking too many Snapchat videos of him.
While not the owner, Perry did work with (by which we mean he appeared in the "Dark Horse" video) the famous Pomeranian Jiff, the world's fastest dog on both his hind and front legs, according to The Daily Mail.
It's a good thing Bloom is taking to his girlfriend's animals, because they're obviously her true loves.
