Min Hyorin and Shinbi Woori want to become the Korean equivalent of Hollywood’s Olsen twins. Even though these two girls are not biologically related, many believe they are actually twins. At the Mnet KM Music Festival event, comedian Shin Dong Yup could not hide his surprise when he saw these two together.

Min Hyorin and Woori will travel to 10 different cities in 7 different countries to film a show titled Korean Olsen Twins, which features fashions and trends of each city. Korean Olsen Twins will air on Mnet January 2008.

Will Mary-Kate Olsen, who is in the hospital with a kidney infection, and Ashely Olsen, sue Hyorin and Woori for trademark infringement? Maybe, and maybe not.

The New York Daily News reports that the girls had extra security measures in place at their birthday bash.

The Olsen twins demanded that guests check cell phones and BlackBerrys at the door at their 21st-birthday party Friday, lest any illicit pictures get out and ruin their six-figure asking price for photos.

As if these two aren’t already making millions for their likenesses and the endless array of Olsen Twin products.

Now their own friends can’t memorialize that time they held back the hair of both twins as their celebratory woo-woo shots came back up?

This is a slippery slope. What’s in store for Mary-Kate and Ashley’s future partying pals?

Confidentiality agreements? Blindfolds? Memory-loss drugs?

Mary-Kate and Ashley Olsen turned 21 yesterday, reminding us all that we’re getting very, very old. These two former child stars have gone from annoyingly cute infants to troubled teens before our eyes over the years.

Maybe opting to stay out of trouble, the girls decided to celebrate their big b-day at a small party with family and close friends. They even spent most of the day taking a break from being celebrities:

"Today, for the first time in a looooong time, we’re taking a day off – doing absolutely nothing and looking forward to every second of it!"

Happy birthday, Olsens. It’s all downhill from here.
