J.Y. Park’s Own Song Beats Miss A’s Track, Suzy Playfully Calls Him a “Bad Boss”

Ten years ago, singer and JYP Entertainment’s head producer Park Jin-young (J.Y. Park) rose to dominate the music charts, even surpassing girl group Miss A from his own label.
On April 12, 2015, Park Jin-young released his digital single album 24/34, featuring the title track Who’s Your Mama? — a song that openly praises women with a 24-inch waist and 34-inch hips. Rapper Jessi featured on the track, adding to its bold flair.

Just like the song’s provocative description, the music video was equally striking. Model Lee Hyun-ji starred as the female lead, drawing massive attention. It was reported that over 200 models auditioned for the role, with the production team carefully selecting someone who perfectly fit the concept of the song.
Lee Hyun-ji, who had previously earned nicknames like “Han Chae-young’s Doppelgänger” and “Korea’s Jessica Gomes” for her stunning figure, ultimately won the role. She had also placed in the 2013 Miss Maxim Contest. Appearing in a bikini in the video, Lee Hyun-ji fully embodied the sexy yet playful spirit of Who’s Your Mama?, making a huge impact.

The song quickly became a sensation, sweeping first place on major Korean music charts within a day of its release. Impressively, it overtook Miss A’s Only You, another major JYP release at the time. During the fourth week of April 2015, Who’s Your Mama? ranked No.1 while Only You placed second on the Melon weekly chart.
In response, Miss A’s Suzy cutely posted on her personal account, “Bad boss!” along with a screenshot showing Who’s Your Mama? topping the charts over Only You.
Park Jin-young playfully replied, “You’re partly responsible too since you recommended working with Jessi, so don’t be too mad!”
Park Jin-young and Miss A shared a strong bond during their time together at JYP Entertainment. As their producer and mentor, Park Jin-young personally guided the group’s music and performances, helping them achieve massive success with hits like Bad Girl Good Girl. Their relationship felt more like family than business, filled with mutual respect and playful moments.
