The "Eat" singer teamed up with HaHa to compose a song called "Sponsor," a guitar-laden track that features Zion.T's very own father. At one point in the lyrics, Zion.T inserted his own personal phone number much to the shock and joy of fans! Zion.T had actually planned with HaHa to reveal his number during today's performance, which took place at Pyeongchang's Alpensia Resort. 

After his stage was over, Zion.T said in an interview, "I will answer the phone for a week after this but after that I will change my number." HaHa joked, "Everyone, please give Zion.T a call." 

The music festival will broadcast this coming August 22 and 29 so be sure to tune in to check out Zion.T and HaHa perform together! It's too bad that Zion.T will have changed his number by then...
