Barbie is nearly 60 years old, yet we only just learned a very basic piece of information about the iconic doll: her last name.

Though she originated as an unrealistically proportioned blonde with a perpetual smile on her face, Mattel’s wildly popular doll has come a long way as a feminist icon.

The Wisconsin native traveled into space in 1965, ran for president six times beginning in 1992 (though she has yet to win an election), broke the “plastic ceiling” in 1985 when she became a business executive, and has entertained more than 180 careers in her 59-year lifetime. Oh, and her last name is Roberts.

Barbie made fans’ heads explode when they tweeted an image of the “Roberts sisters” on National Siblings Day.

As it turns out, Barbie is not the Madonna of children’s toys. She has a full name, and it’s Barbara Millicent Roberts.

Barbie’s longtime boyfriend (and occasional husband), Ken, has a last name as well: Carson. Despite the many Barbie and Ken wedding collections released over the years, it seems Miss Roberts kept her maiden name.
