Call her this year's pop-culture prom queen.
A year ago, Miley Cyrus was no stranger to us, of course. But who could have guessed how her star would rise — or rather, explode — in 2013, making this former preteen idol one of the most watched people on the planet? And so it seems only right to make Miley our tour guide (Kim and Kanye, you came close!) as we take our annual, highly selective, chronological tour through the year's pop culture moments:

JANUARY
A new year brings an inauguration in Washington, D.C., but even the president admits the weekend's most important development is a bouncy new hairdo — bangs! — for MICHELLE OBAMA. Mini-scandal: BEYONCE sings the national anthem, only to admit later she lip-synced. At the Golden Globes, JODIE FOSTER makes an awkward, rambling but deeply compelling speech, hailed by many in the gay community as her long-awaited coming-out. LANCE ARMSTRONG confesses — to OPRAH WINFREY. Meanwhile, KIM KARDASHIAN basks in the glow of her just-announced pregnancy (proud dad is KANYE WEST) and says she looks forward to privacy — good luck! MILEY CYRUS, beginning her big year, is happily ensconced in her engagement to LIAM HEMSWORTH ...
FEBRUARY
Or is she? It's Oscar time, and MILEY, in a sexy backless white dress, makes news for who she ISN'T with at a post-Oscar party — her fiance. The Oscars bring triumph to BEN AFFLECK and "Argo," his somewhat-true movie about a truly fake one. And they bring us a new sweetheart: JENNIFER LAWRENCE, who trips onto the Oscar podium and into our hearts. Elsewhere, BEYONCE admits her inauguration lip-syncing, then rocks the SUPER BOWL with a spectacular halftime show, sung live, of course ...
MARCH
Things are heating up for MILEY — she's the March Cosmo cover girl. Of her major image change from those HANNAH MONTANA days, she notes: "Some of the worst things that have happened in my career ... have actually been what's best for me." That would be music to JUSTIN BIEBER's ears. In a bad start to a bad year, the 19-year-old pop star is booed by fans when he shows up late to a concert, struggles with his breathing and faints backstage at a show, is caught on camera clashing with a paparazzo, has his pet monkey confiscated by German authorities when he fails to produce proper papers ... and it's only March!
APRIL
Remember KIM KARDASHIAN's five-minute marriage to NBA star KRIS HUMPHRIES? No? Well, the couple's divorce comes through. GWYNETH PALTROW makes waves at the "Iron Man 3" premiere in a dress with see-through panels on both sides, leaving little of her lower body to the imagination and embodying a trend of bare skin on red carpets. It's clearly working: This month, she's named People magazine's Most Beautiful Woman. MILEY's ever-changing style morphs again: She seems to be ditching her engagement ring and is wearing longer hair with side bangs ...
MAY
But not for long! It's all bleached, spiky hair for Miley at the punk-themed Costume Institute Gala at the Metropolitan Museum of Art, where she hobnobs with the fashion elite, cementing her status as someone we're watching this year. At the Cannes Film Festival, a real-life jewel robbery makes headlines, partly because it coincides with Sofia Coppola's new movie, "Bling Ring," about young bling thieves. BIEBER's monkey officially becomes German property.
JUNE
Time for a KIMYE update, and it's a biggie: a daughter is born! The couple name her North West, inviting inevitable comparisons to other oddly named celebrity progeny (Apple Martin, anyone?) MILEY watch: "We Can't Stop" is No. 4 on Spotify's most-viral list. Oh yes, and Miley's dad, BILLY RAY CYRUS, is getting divorced from his wife of 19 years, Tish Finley Cyrus. But wait ...
JULY
Never mind — the divorce is off. More important, we have a royal birth! As she emerges from the hospital holding Prince George, it's noted that KATE MIDDLETON, aka the Duchess of Cambridge, isn't concealing her "mommy tummy," a development cheered by fellow moms across the world. On the KIMYE front, President Obama doesn't help get himself on the Christmas card list when he notes that in his day, "Kids weren't monitoring every day what Kim Kardashian was wearing or where Kanye West was going on vacation, and thinking that was the mark of success." Ouch! MILEY gets a documentary on MTV, "We Can't Stop" is No. 2 on Billboard's Hot 100 chart, and she says in an interview: "People just evolve, and that's all that's happened to me."
AUGUST
Maybe this is what she meant by evolving? August is the month MILEY will be remembered for most, thanks to her infamous performance on the MTV Video Music Awards, where she twerks her way into pop culture history in a teddy bear leotard that segues to a skimpy nude bikini. Of course, there's the foam hand, too, the constantly stuck-out tongue and the vulgar gestures. By morning, we can't talk about anything else. We'd like to stop ... but we can't!
SEPTEMBER
An "it" girl of the Hollywood-fashion nexus becomes even hotter. TV's "Scandal" actress KERRY WASHINGTON makes glamorous appearances at New York Fashion Week, where she judges "Project Runway" in a pretty Stella McCartney floral number, and at the Emmys, in an eye-catching Marchesa gown. MILEY watch: Her reps confirm her engagement to Hemsworth is off ...
OCTOBER
But hey, KIMYE's getting hitched! WEST proposes to Kardashian at the AT&T Park, home of the San Francisco Giants, with a screen reading: "PLEEEASE MARRY MEEE!!" He also makes an uncomfortable appearance with Jimmy Kimmel, an effort to defuse a feud stemming from a parody skit. MILEY hosts "Saturday Night Live," playing a salacious version of Michelle Bachmann. Maybe it's not a great idea to give MILEY advice: After Irish singer SINEAD O'CONNOR counsels her publicly to avoid being sexually exploited by the industry, MILEY strikes back on Twitter, mentioning O'CONNOR's struggles with bipolar disorder.
NOVEMBER
Time for some year-end awards. "Twerk" is on the shortlist for the Oxford Dictionary word of the year, though it loses out to "selfie." People magazine's Sexiest Man Alive is singer ADAM LEVINE. On the GQ annual list of least influential celebrities, Miley is No. 6, but don't feel TOO bad, Miley, President Obama is No. 17. At the American Music Awards, meanwhile, MILEY doesn't disappoint, performing "Wrecking Ball" as a duet with a giant, lip-syncing CGI kitten.
DECEMBER
More nods to MILEY's pop-culture dominance: MTV names her artist of the year. As for KARDASHIAN, she ranks No. 3 on GOOGLE's list of most-searched people in the U.S., the only non-singer on the list. Fiance West is No. 10. And Google's No. 1 is ... come on, did you have any doubt? MILEY also tops Yahoo's most-searched list. (KARDASHIAN is second.) And, as the year ticks to a close, guess who's going to be rocking out in Times Square?
Happy MILEY Year.
