Line of Duty actor Adrian Dunbar shared a sweet photo of his granddaughter wearing an AC-12 sleepsuit - and fans went wild.
The Northern Irish TV star, who plays Superintendent Ted on the BBC1 drama, enjoyed cuddles with little Zephyr while showing off her special cop uniform on Instagram.
Fans went into meltdown as they noticed the adorable tot was wearing the garb, making reference to her granddad's beloved TV character.
His daughter Madeleine had captioned the series of cute snaps of her little one and dad: "Zephyr repping her Grandpop."
Her followers flooded the comments section with delighted messages.
Adrian's co-star Vicky McClure shared: "Aww adorable pics!! xxx"
A fan penned: "This may be the cutest thing I've ever seen!!"
"Your dad looks a very happy and proud man x" a third added.
Others labelled Adrian's granddaughter as "adorable".
Adrian's beloved daughter Madeleine, 34, gave birth in December, telling fans she welcomed a 'perfectly cooked' baby girl.
Madeleine broke tradition and proposed to Callum last year but their romantic moment didn't quite go to plan when she got down on one knee.
The songwriter, who met her beau on Bumble, got down on one knee outside the Oxo Tower in London to ask Callum to be her husband.
However the momentous move was cut short after police were called on the pair for trespassing on a jetty on the River Thames.
Madeleine chose the spot because it was where she and Callum had shared their first kiss, however she didn't realise it had since been closed off to the public.
She said: "I was really nervous as I’d been waiting on this jetty for an hour. Callum sat down next to me and I got out an Irish Claddagh ring from a jewellery bag.
"But I was down on my knee declaring my love for this man when I heard a security guard shouting at us, telling us we were not supposed to be there and that they were calling the cops."
After being told police were on their way, Madeline and Callum scarpered and the songwriter admitted she broke down with the emotion of it all.
She said: “I just started bawling. I was crying and crying and crying because the moment was spoiled.
“But Callum said, 'Don’t worry. Yes, I will marry you’ and he let me put the ring on his finger.”
