This dog takes personal grooming very seriously.
A pooch this stylish can't pound the pavements of NYC's West Village with a shaggy barnet.
He and his fashionista owner have a reputation to uphold.
We see tons of crazy images of celebrities but it's been a while since one has been such a topic of conversation at Sky Living HQ.
To put it simply, we are obsessed with this dog.
Olivia Palermo and her pup Mr Butler were papped on one of their daily walks, and we just can't get over Mr B's haircut.
It makes his head look rather large and cartoon-like, and he must be pretty chilly without his natural fur coat.
We're not too sure why he's called Mr Butler - perhaps the pup is really good at helping Olivia out around the house?
But one thing's certain. This dear little pooch is definitely upstaging his stylish owner.
Just last week were in awe of Billi Mucklow and Cara Kilbey's dogs on TOWIE, who were taking part in a yoga session as the stars chatted away.
They were also seen walking their dogs through the park in a pram. (Wrong.)
Mr Butler has no desire for such extravagances, however - just a trendy haircut and this season's collar.
While we obsess some more about our new favourite celebrity, come and check out more pictures of stars and their pooches...
