This week marks the 15th anniversary of “…Baby One More Time” dropping, creating a megastar of the plaid schoolgirl outfit-wearing Britney Spears. Since then, Spears has transcended the music world to become a cultural icon. Love her or hate her, you know every word to “Oops!… I Did It Again” and you will never forget when Britney and Justin Timberlake wore matching Canadian tuxedos to the 2001 American Music Awards (OK, maybe that’s just me). Now that we’re getting nostalgic, let’s reminisce on the highs and lows of her unforgettable career.

1. January 1999: The arrival
The 17-year-old’s first album “…Baby One More Time” debuts at No. 1 on the Billboard 200, and the title single with its Catholic schoolgirl-inspired video hits No. 1 in the US and every country in which it charts. And so the domination begins.

2. March 2000: She does it again
Britney tops the charts again when she ditches her school uniform in favor of red jumpsuits and astronauts and releases her sophomore album “Oops!… I Did It Again.”

3. September 2000: The nudie suit
Brit delivers her first of many iconic performances at the MTV Video Music Awards (VMAs), during which she rips off a black tuxedo and reveals a flesh-colored sequin jumpsuit. The world becomes officially convinced that she’s not that innocent and the look goes down in Britney history.

4. September 2001–November 2001: Singing with a snake
Britney delivers show-stopping VMA performance No. 2 singing “I’m a Slave 4 U” while wearing little more than spandex short-shorts and a live python. The performance causes every man and woman on the planet to crush on Spears, pushing her third album, “Britney,” to the top of the charts.

5. February 2002: Failed movie star
The pop princess hits the big screen as the star of “Crossroads.” I know, I like to pretend that didn’t happen, too. Let’s just move on.

6. May 2002–June 2002: First heartbreak
Young girls all over the world stop believing in love when Britney Spears and Justin Timberlake call it quits after three years of dating. But in June, Britney proves she don’t need no man and tops Forbes’ Celebrity 100 List as the most powerful celebrity of the year. Ladies and gentleman, please bow down to your ruler.

7. August 2003: The Madonna kiss
Britney locks lips with Madonna while singing “Like A Virgin” at the 2003 VMAs. Seconds later, Christina Aguilera does it too, but we are all too busy looking at Britney to notice.

8. November 2003: Grammy breakthrough
Britney drops her fourth album, “In the Zone,” and becomes the first female artist to have four albums debut at No. 1. The album’s single “Toxic” gives Britney her first and only Grammy. That’s a lot of firsts.

9. January 2004: First marriage
Britney forgets that legally binding ceremonies that happen in Vegas don’t stay in Vegas and marries childhood friend Jason Alexander at the Little White Chapel. Fifty-five hours later, her people get the marriage annulled. Problem solved.

10. September 2004 – November 2006: Oops!…She marries again
Britney marries frog No. 2, back-up dancer Kevin Federline. The couple has two kids, Sean Preston and Jayden James Federline, and stars in the reality show “Chaotic” (yeah…file that one in the “Do Not Open Folder” with Crossroads) before Spears files for divorce in November 2006. The divorce is finalized in July 2007.

11. February 2007 – October 2007: Uh, what?
In February, Britney checks into rehab in Antigua for less than a day. The next day, she’s spotted shaving her head in Los Angeles, and spends the next several weeks in various rehab facilities. In October, Britney loses physical custody of her children. She also releases her fifth album, “Blackout,” and even though it was her first album not to debut at No. 1 (it landed at No. 2), its single “Gimme More” gives us the tagline to end all taglines: “It’s Britney, bitch.”

12. January 2008: Sad spotlight
Britney is hospitalized at Cedars-Sinai Medical Center in Los Angeles and has visitation rights to her children suspended. She’s placed under temporary conservatorship of her father James Spears and attorney Andrew Wallet.

13. December 2008: The comeback
Britney drops her sixth studio album, “Circus.” It debuts at No. 1, making Britney the youngest female artist to have five albums debut in the top spot and earning her a place in Guinness Book of World Records. Its single “Womanizer” is Britney’s first No. 1 hit on the Billboard Hot 100 since “…Baby One More Time” came out 10 years earlier. Britney is back, bitches.

14. November 2009: Record breaker
Three proves to be a lucky number for Brit Brit after all. Her song “3,” the only single off of her greatest hits album “The Singles Collections,” becomes her third No. 1 Billboard 100 single.

15. March 2011: Another comeback
After a relatively quiet year for the pop princess and with her personal life back on track, Britney releases her seventh studio album, “Femme Fetale.” It peaks at No. 1, tying her with Mariah Carey and Janet Jackson for the third most number ones among women. Successful career comeback No. 2? Check.

16. August 2011: Lifetime honor
If Britney giveth, then she shall receive: After years of delivering iconic performances at the VMAs, the award show honors Brit Brit with the MTV Video Vanguard Award, a lifetime achievement award.

17. May 2012: TV judge
Britney is added to the judges’ table on “The X Factor,” becoming the highest-paid judge in the program’s history. During her one season with the show, she serves as a mentor for its teen category, obviously, because nobody knows more about teen stardom than Britney.
