if i am not mistaken she is a model for rihanna's beauty brands

Christelle Mangaya fired some shots on her storyline to the "haters" lol....

I still think Mopao is stretching the truth.
Didi is a beauty influencer/IG model. A lot of IG influencers are invited to these kind of events to promote whatever brand or artist has to sell to create some kind of buzz on social media. Even if it included a photo op.
In this case it's Rihanna clothing line.

I like the maturity Didi exhibited. It would have been tempting for her to say "You can all go and hang yourselves you haters" Anyway she's not Congolese, French.
