Grand P, whose real name is Moussa Sandiana Kaba, was born with progeria, an extremely rare genetic disorder that has affected his physical stature. Plus-size model Eudoxie hit back at trolls saying they were an unlikely match. She says they are very happy together, adding "the physical doesn't count".

Taking to Instagram, where she has nearly 1 million followers, Eudoxie wrote: “We are happy together, and this is the most important thing. Thank you, everyone, for your support. The physical does not count in a relationship.”

Grand P lives life to the fullest and surprised fans by entering into a relationship with the Ivorian model who he also plans to wed. However, in another post last week, Yao appeared to warn her fiance to stop playing the field.
