Those Kardashian/Jenner girls don't waste any time, do they?

Kylie Jenner, a teen model whose image has appeared on the pages of Sears catalogs and in Forever 21 advertisements, has snagged her first boyfriend -- Australian crooner Cody Simpson.

Teen Twosome Alert! Move over Justin and Selena, there's a new -- even younger -- kiddie couple in town! Cody Simpson, an Australian pop tart of Bieber proportions over in The Outback, is rumored to be dating Kylie Jenner, teen model and the youngest sister of The Kardashian Klan. He isn't a skyscrapping basketball player or a douche-y businessman in a three-piece suit , but we think Kourtney, Kim and Khloe will be impressed just the same.

They're kinda easy that way. 

The 14-year-olds were spotted "flirting" with each other at the Los Angeles premiere of The Twilight Saga: Breaking Dawn -- Part 1.  Kylie and her sister Kendall interviewed Cody on the red carpet for an Internet podcast. Sparks flew almost instantly, spy-witnesses recall, with Kylie even referring to Cody as her "Rumor Boyfriend" and admitting she would "marry an Australian." The kids have apparently been inseparable ever since. Making for quite the adorable duo, Kylie  and Cody were spotted out and about together over the weekend, even hitting The Grove in Hollywood for a post-Black Friday holiday shopping spree.

"Yes, they went on a date. I would say they are dating. They are a couple! They are so cute together," a squeal confirmed to Us Weekly Monday.

Hey, if they make it to January, Kylie and Cody's romance will already have a longer shelf life than Kim's marriage! Think age 14 is a bit young for dating? Maybe here on Earth -- but in case you haven't heard, we Earthlings have a thing or two to learn about life on Planet Kardashian. Kylie's older sister Kendall was about that age when she was romantically-linked to The Biebs. Those whispers ultimately set off a rumored love triangle between Bieber, Jenner and the singer's cute-as-a-button girlfriend, Selena Gomez.
