Only or just happened to find happiness with a black man? I only know of Doutzen Kroes to have dated black men even before marrying Sunnery. The first girl I can't seem to find anything about her dating black men so pictures could help. lol. But Doutzen has dated DJ Ruckus And before DJ, she was with Maxwell in 2006 So Doutzen has been with black men since 2006, for around 12 years now. Her and Sunnery have been together since 2010 and married for 7 years.
I saw a video weeks ago that mentioned that top 4 plus-size models in the world (Iskra Lawrence, Nadia Aboulhosn, Denise Bidot, & Ashley Graham) were all married or dated BM. EDIT: It was this MBD video:
