One of the special treats that come with Mighty Mouth tracks are their surprising guest features of actresses, such as Han Ye Seul and Yoon Eun Hye (although she was previously a member of Baby V.O.X). Mighty Mouth also boasts guests from top-line vocalists like Baek Ji Young and Insooni, and fans love their style of soft pop/hip-hop. This time though, Mighty Mouth's new "guest" is garnering bigger attention than their previous stars, and it's one of Korea's most known actresses, Kim Hee Sun. Her feature on Mighty Mouth's upcoming track, "Love Is", is amassing attention because fans are hoping this is a stepping stone to Kim Hee Sun's return to the industry after being absent since 2006. Kim Hee Sun does boast some amazing vocals, as she showed on MC Mong's "Truth from Heaven (ft. Kim Hee Sun)". She also covered Natalie Cole's "Love" in 2005. Source + Photos: Newsen
