Korean actor Lee Min-ho has warned fans of a fake Twitter account opened up under his name, according to his agency Starhaus Entertainment.
"What people currently know as Lee Min-ho's Twitter is a fake account," said an official at Starhaus on Friday, adding that they are preparing countermeasures to protect the actor's fans.
Lee currently has about 70,000 followers under his account -- more than any other Korean celebrity in the country.
An account can be opened with just an email address and ID on Twitter, a popular U.S.-based online social networking and microblogging service.
Many other overseas and Korean stars including pop groups Girls' Generation and singer Son Dambi have reportedly been taken advantage of by people who opened up accounts in their names.
Lee, 22, shot to stardom throughout Asia after starring in the smash hit TV series "Boys Over Flowers" last year alongside actress Koo Hye-sun and idol group member Kim Hyun-joong of SS501.
He is scheduled to appear in upcoming MBC TV series "Personal Taste", which premieres on March 31, opposite actress Son Ye-jin.
