She’s everywhere. Currently, she’s sitting atop the box office in her perfect pink dress and tasteful pink heels.

She is, of course, the doll turned movable turned movie star turned absolute mogul. It’s her world, and we’re all just living in it.

I speak, of course, of the one, the only — BARBIE.

I loved her as a child. What little girl didn’t? She was the original cool girl of the plastic world.

I’ve got to give my girl her props as she invades the planet in a whole new way, via movie theaters near you.

According to “Hot Topics,” an online entertainment site, here’s the 4-1-1 on “the one.”

The brainchild of Ruth Handler, co-founder of the toy company Mattel, allegedly she was inspired by her daughter playing with make-believe paper dolls of adult women.

Barbie’s appearance was modeled after a doll named the Bild Lilli, which had been inspired by a German comic-strip character. Originally marketed as a racy gag gift that men could buy in tobacco shops, the Lilli doll later became extremely popular with children. Mattel bought the rights to Lilli, and Handler created her own version.

Her official birthday is March 9, 1959 — the day she was officially introduced to the world. Makers touted Barbie as a reflection of the times, with the first doll mimicking the glamour of 1950s stars such as Elizabeth Taylor and Marilyn Monroe.

In its first year alone, 300,000 Barbie dolls were sold. The premier Barbie doll sold for $3, but a mint condition No. 1 doll can fetch more than $25,000 today.

Barbie has had more than 250 careers. She broke the plastic ceiling when she went to the moon in 1965, four years before Neil Armstrong. Since then, she has been everything from a doctor to a paleontologist to a rock star to a computer engineer.

To counteract criticisms that Barbie was solely a sex symbol, Mattel gave her a best friend, Midge Hadley, introduced in 1963. A year later, they gave her a little sister, Skipper Roberts.

In 1967, supermodel Twiggy became the first celebrity to have a Barbie made in her likeness. Cher, Audrey Hepburn, Diana Ross and JK Rowling — to name a few — later would join the ranks of celebrity Barbies.

While there had been other African-American dolls in the Barbie collection before — including Barbie’s friend Christie, first introduced in 1968 — an official African-American Barbie wasn’t created until 1980, alongside a Latina Barbie. That same year saw the first of more than 40 different international Barbies released to date.

To this day, Bob Mackie Barbie dolls are some of the most sought-after collectibles. Featuring the fashion designer’s trademark glam style, the Bob Mackie Gold Barbie featured 5,000 hand-sewn golden sequin accents.

Barbie’s on-again, off-again longtime boyfriend, Ken Carson, was introduced two years after Barbie in 1961. Ken was named after Ruth Handler’s son.

“Tragedy” struck in 2011 when the duo embarked on a seven-year itch of sorts — they broke up. Aw, don’t worry, after seven years apart, Barbie and Ken reunited and the rest? Plastic history, natch.

For the record, I have always loved Barbie, but Ken? Eh. Call me kooky; I can live without him.
