Miley Cyrus has gotten the seal of approval from Patrick Schwarzenegger's sister Katherine Schwarzenegger!

During an interview with Extra, the 25-year-old gushed over her little brother's pop star girlfriend.

"I think they're adorable," Katherine said of the cute couple. "If my brother's happy, I'm happy and that's all that matters to me. You just want your sibling to be happy, if they're with someone who makes them happy and in a happy healthy relationship then I'm happy."

Speaking of the "adorable" lovebirds, a source tells E! News that Miley and Patrick's relationship is getting ‘'very serious."

The insider adds that the 21-year-old hunk's mom Maria Shriver really likes the 22-year-old "We Can't Stop" singer and thinks she is a terrific girl. In fact, Miley, Patrick and Maria all had dinner together earlier this week. The twosome was spotted leaving The Palm restaurant in Beverly Hills Wednesday following their family meal.

As for their date night attire, Miley looks cute and conservative in a black knit dress and black boots while her beau looked hunky as usual in blue jeans and a sweater.

It's nice to hear the cute couple are stronger than ever after nearly five months of dating!
