I don't understand why it's funny
So there's an age difference. Big deal. I don't understand why age continues to be discriminated against when we've come so far with interracial and same-sex romances. If someone posted that Ellen DeGeneres and Portia DiRossi split and laughed about it and said "big surprise, they're both women" I don't think the reaction would be very positive.
I like them both and thought they were really cute together. I've seen Katie on some cooking shows and she is adorable.
That's too bad. I hope they can work things out.
