Popular 4th Generation Idol Addresses Allegations Of Contouring Chest
ZEROBASEONE’s Matthew has officially addressed an allegation that recently stirred online communities — claims that he had “contoured” or shaded his chest area for performances.

Speculation started after close-up photos and fan-taken videos from a recent stage made his upper body appear more defined. A fan suggested that makeup had been applied to enhance his chest.
