The reality TV star's French bulldog has become well known for being an adored pooch on the set of Made In Chelsea, after Millie initially had to give him up because she wasn't able to keep dogs in her apartment building.
However, she managed to get him back and now it looks as though the pair are inseparable, with Herby making himself at home at the house Millie shares with her rapper fiancé, Professor Green.
And Herby's even accompanying his beloved owner to work now too!
He was spotted posing beside 23-year-old Millie in her daily 'style diary' blog feature, which sees her update her fans on what she is wearing and where you can buy her outfit.
At one point the adorable pooch finds himself in Millie's arms, as she cuddles up to him for a super cute snap.
While a number of women might be a little sceptical of giving their pet a big squeeze when they're wearing a fancy frock (especially if it's white!), Millie didn't seem to mind and she even tried to pucker up for a kiss - although Herby didn't look too keen!
Millie is pictured wearing a figure hugging white dress with polkadot detailing from Ukulele, a statement head chain from River Island and pretty white Zara heels.
Unfortunately, it sounds as though these photo shoots are the only way we are going to be able to catch a glimpse of Herby and Millie together from now on, as the Quality Street heiress has quit Made In Chelsea in a bid to keep an element of privacy in her life.
According to her fiancé Pro Green, Millie was being pushed by the show's producers to film more personal scenes, which she wasn't too happy about and ultimately she decided to leave the BAFTA-winning series.
Well, we suppose she does have a wedding to plan!
