You think thta James Allen would sponsor ring for Dakota if it wasnt about Brooklyn fame? So its same thing. They had to ask Brooklyn and Bailey if they want a colab, sing some paper about working togegher, promoting it, how many posts on insta amd youtube. Its their chanel, not Dakotas soo... if they will rich out to Dakota, give him a ring for free and Brooklyn would say 'no, im not going to advertaise it on my chanel' than what? So bassicly she paid for her ring by herself, she is the one who signed agreement with the company about adertising it on her social media.
