Actor Lee Min-ho attended an autograph-signing event to promote fashion brand Guess, for which he is currently modelling, on Friday.

Lee met fans in Seoul at the American brand’s flagship store in Garosu-gil.

Lee, 27, has modeled for Guess since last August. The actor wore casual clothes by the brand for the event, including a black sweater with the face of a chihuahua on it.

The fashion event was Lee's second public appearance in Korea since reports broke two months ago that he was in a relationship with K-pop singer Suzy, following his presiding over the first day of the three-day Lotte Duty Free festival, Friday.
