I have no idea what Khabib's wife looks like, but I think you most likely don't either. Afaik there are two pics out there which often are claimed to be "Khabib & wife". One is just a shoop and the other is him standing next to a russian celebrity. As for the latter pic he has explicitly denied to be married to that person. Look at this thread http://forums.sherdog.com/threads/khabib-denies-rumors-i-am-not-married-to-olga-buzova.3870829/ , I guess that's probably the pic you were talking about, weren't you?
