The 25-year-old model recently talked to People, where she opened up about her father's relatively private relationship with Holmes.
"They are so great and Katie is always so chic. They were wonderful," Corinne replied when asked about Jamie and Katie's Met Gala looks. "[It was] my dad's first Met Gala," she added, joking that she felt "cool" because she got to go to the annual fashion event before her dad.
While the two didn't walk the red carpet, they did pose for photos once inside the event. Katie looked stunning in a royal purple gown with a fuchsia feathered collar while Jamie seemingly matched the actress' color scheme, rocking a traditional black suit which he paired with bright purple shoes, the same exact shade as Holmes' ensemble.
Meanwhile, Corinne had nothing but amazing things to say about her dad and Katie. "They're really good, really great," she shared.
As far as getting to spend time with Katie and getting to know her, Corinne said she had, and that the actress and her father are "really happy." Last month, Jamie, Katie and Corinne were all spotted catching dinner and a movie in Los Angeles.
Katie and Jamie have reportedly been dating for nearly six years, though the two have never confirmed the romance on their own.
