This is all bullshit so that both of them can use it for publicity.
There is no way that these two are really a couple, it's a relationship purely for the media and self-promotion purposes.
There is also no way that Bruce has had the chop, even though he claims that he has.
Bruce is as heterosexual as they come and his whole transgender schtick is solely to make money and get rewards from those powerful people who want to push the transgender agenda. He has admitted in interviews to still being attracted to women, and remember when he pissed off Ellen by refusing to dance with her? She said she felt it was because she was a dyke.
What 21 year old model is going to want to date Bruce in a wig and a dress? Even a transgender one wouldn't go near an old fuck like that. It's a mutual publicity stunt, Sophia Hutchins is a model and this stunt puts him up into the Kardashian universe and gets him more publicity than he could have ever gotten alone. Bruce also does it to keep his name in the celebrity headlines.
A sham relationship by a couple of complete shams.
