SISTAR member Hyolyn is branching out from K-pop to hip-hop.

The popular girl group member has been revealed to be collaborating with rappers Zico and Paloalto of "Show Me The Money 4" for a special upcoming hip-hop track.

"Hyolyn, Zico, and Paloalto will be releasing a special project to be released at the end of this month," said SISTAR's agency Starship Entertainment in a statement on Thursday. "They are preparing a hip-hop collaboration that will be on a whole new level."

The 24-year-old singer has previously collaborated with other Korean hip-hop artists with great success. In 2013 she appeared on the Dynamic Duo track "Hot Wings" and in 2014 she collaborated with Mad Clown for "Without You" and MC Mong for "Faulty Fan."

Zico and Paloalto are currently appearing as judges on Mnet's rap survival program "Show Me The Money 4."
