Praising the couple's strong relationship, she says she has no problem with Miley's wild antics because she makes her sibling "happy".
Speaking to Mario Lopez on Extra, she explained: "I think they're adorable. I mean if my brother's happy then I'm happy and so that's all that matters to me."
The couple have been dating now for almost a year, but were thought to be receiving pressure from Patrick's family to split, with rumours suggesting they believed she was a bad influence on the youngster, but Katherine's revealed she's pleased he's now found someone to love.
"You just want your siblings to be happy so if they're with someone that makes them happy in a happy and healthy relationship then I'm happy."
She went on to open up about her own home life, and said her mother's strict when it comes to her children using their mobile phones during family dinners.
"She makes us all put our phones in the centre of the table so no one is on their phone. It's such a good rule because you do see people, especially couples on dates, and they're all on. It's so sad."
