Beyonce and Jay-Z got into the Halloween spirit as they all dressed up as Disney's The Proud Family.
The Single Ladies singer wore not one, but two outfits for the group photo - where she dressed up as the grandmother and the head of the household.
Sharing the snap with her 281million followers on Thursday, she captioned the snap: "Family every single day and night."
Fans said how they "had to do a double take" after realising that Queen Bey was also in costume as the wise-cracking grandma, Suga Mama.
For her transformation into the sharp-tongued granny, she wore a grey wig and a pink cardigan with a large Peter Pan collar.
Her outfit revealed a silver pleated skirt that went all the way down to the floor. She also added a walking stick and large framed glasses - just like the Disney animation.
For her second character, Trudy, she slipped into a pair of figure-hugging sparkly orange trousers and a yellow corset.
She added a lime green blazer for good measure, and a short wig chopped into a bob.
Hubby Jay-Z put just as much effort into his costume as Oscar, the family's goofy dad.
He wore a pair of blue trousers, with a shirt and tie - and even wore braces.
And of course, Halloween isn't just for excited celebrities - their kids, Blue Ivy, 10 and twins Rumi and Sir, five, also got into the spirit.
Blue, who is the spitting image of her mum, transformed into the show's main character, Penny - who rocks thick pigtails.
Her siblings became Penny's mischievous younger siblings BeBe and CeCe - who are also fraternal twins.
The cartoon aired from the early 2000s and ran for three seasons until 2004 when it ended.
Noting the delay in her post, one fan wrote: "ONLY BEYONCE CAN POST 3 days AFTER HALLOWEEN"
Another added: "Cooler than the other side of the pillow."
"THE CARTERS GON EAT EVERY TIME!! WE GOT 2 BEYONCÉ’S IN ONE PIC! JAW DROPPED," a third chimed.
Just last week the Carters headed to the Wearable Art Gala in Los Angeles.
While the twins stayed at home, Blue Ivy joined her parents to the swanky event.
