Josh Cullen Santos was born on October 22, 1993, better known by his stage name “Josh” and “JOSH CULLEN”, is a Filipino singer, songwriter, producer, songwriter, dancer, and a professional gamer. He is the lead rapper of the Filipino boy band SB19 managed under 1Z Entertainment.

On October 26, 2018, Santos debuted with fellow members Pablo, Stell, Justin, and Ken as P-Pop group known as SB19. Their debut single “Tilaluha” was written by fellow member Pablo but its success was not widely acclaimed. With a message centered on heartbreak and unrequited love, the song was intended to introduce the band and their powerful vocals in which it debuted poorly to charts. SB19’s second single “Go Up” was released on July 19, 2019. They described the song as their “last shot” because they had decided to disband if their career did not progress after.

In 2022, Josh joined his independent musician cousins Ocho the Bullet and Carrot Mayor on their track “Sofa (Remix)”, released on YouTube and Apple Music.

On February 24, “JOSH CULLEN” made his debut as a solo artist, releasing a single called “Wild Tonight”. He co-produced the material with Ace Santos, his cousin.
