YG Entertainment's CEO Yang Hyun Suk revealed his grudge with the American pop rock band Maroon 5 on the latest episode of 'K-Pop Star 2'.

When one of the contestants performed a medley of Psy's "Gangnam Style" and Maroon 5's "Moves Like Jagger" on the harmonica, Yang Hyun Suk jokingly commented, "There isn't a good relationship between Maroon 5 and myself."

When pressed, he explained, "Because they're currently blocking the #1 spot on the Billboard charts from Psy."

At the time of filming, Psy was ranking #2 with "Gangnam Style", right behind Maroon 5.
