Yoo Yeon-seok was slapped with a tax bill of approximately 7 billion won ($4.8 million), reportedly the largest ever imposed on a South Korean celebrity

In response to mounting criticism and allegations of tax evasion, Yoo's agency, KingKong by Starship Entertainment, issued a statement on Friday explaining that the tax assessment results from differences "in the way (Yoo's) tax representative and the tax authorities have interpreted and applied tax law."
