Josh lucas is dating
We all likely remember the scene on when Caitlyn refused to dance with a man when she and the other women were taking dancing classes.
When their new next-door neighbors turn out to be a sorority even more debaucherous than the fraternity previously living there, Mac and Kelly team with their former enemy, Teddy, to bring the girls down.
Now, as for why people believe that they are dating ...
well, for starters, they've been hanging out a lot. For example, Sophia has been sharing a lot of photos of Caitlyn's dog, Bertha.
Like a lot of minorities, Caitlyn Jenner is very focused upon respectability politics -- she wants to look and act a certain way that she feels is more dignified.
(That's true of all of us, up to a point, but celebrities who are also minorities feel a powerful added pressure to represent their entire demographic) Cait is also a parent with adult children, so she is also concerned with how her children will feel if she begins dating just a couple of years after coming out to the world and transitioning.
