Blac chyna is the brand ambassador for mac's new fragrance
I think there may be some misinformation here!
After conducting a quick search, I couldn't find any evidence to suggest that Blac Chyna is the brand ambassador for MAC's new fragrance. MAC Cosmetics is a well-known makeup brand, and while they have collaborated with many celebrities and influencers in the past, I couldn't find any information about Blac Chyna being associated with a MAC fragrance.
