The Hunger Games star and former Hannah Montana sensation announced their engagement last month. Luke reveals his two young daughters are in awe of their aunt-to-be, and insists Cyrus has made his sibling truly happy.
"She's great. She loves our kids, and our kids absolutely love her. She won our hearts. I find her really interesting. I find her very articulate, and years in maturity above her age. But at the same time, she's very much like Liam. They actually are a perfect match in a lot of ways," he said.
