Last week, on Siblings Day, as brothers and sisters shared loving and not-so-loving snaps of themselves on social media, toy giant Mattel casually let everyone know that Barbie - THE iconic Barbie - has a surname.
And it's Roberts.
(Yes, that's a young Mila Kuis).
"Happy Siblings Day from the Roberts sisters," said the official Barbie Twitter account, like it was no big deal at all.
Unlike Cher, Beyonce and Madonna, Barbie has not one but two names. And people collectively lost their minds.

While others requested more information
Dear @Barbie,— Jaremi Carey (@PhiPhiOhara) April 14, 2018
100% fully thought Barbie's last name was Mattel......now I am shocked and shook to find out it is Roberts.
Please answer this question......where are parents in the Roberts family and why are they not in the picture.

Some simply didn't know how to feel ...
After 18 years, I finally find out @Barbie has a last name... and it’s Roberts..? 🧐😶 I don’t know how I feel about this.— @ivenka_de (@ivenka_de) April 14, 2018
While others were mind blown that Barbie is short for Barbara ...

According to Barbie's Wikipedia page, (and her Instagram account) her full name is Barbara Millicent Roberts.
She has three sisters, Chelsea, Stacie, and Skipper.
Barbie and Ken, whose last name is Carson, split in 2004. Here they are cooking together a few weeks ago, however, so perhaps there's a reunion afoot?
And, if you feel you can cope with one last piece of Barbie-related trivia - well, she just celebrated her 59th birthday.
