She is brand ambassador. I know in Maybelline, both Yaya and Poo are both ambassadors but for different makeup line.I'm not sure, is she a brand ambassador like Chompoo is or is she just signed on for certain products?. If she's an ambassador then she most likely will be walking at Cannes but it depends on the team etc.
I think you’re right. There’s rumor Mai is replacing Chomp00.All I know is that she's the first(?) Thai ambassador of L'Oreal Paris Makeup for the whole Asia Pacific and she'll be walking the runway at the Paris Fashion Week. (as what I read on IG)
I think it's only for the make-up, the products she's endorsing. If it is (like what you said), then that would be good. She's only filming 1 lakorn right now but she's been in a lot of events lately.
