As she presented the award to Kerr at the gala, Perry playfully teased their family dynamic, telling audience members, "Some of you might be confused about why I'm introducing Miranda. That doesn't play into the antiquated narrative of ex-wives and new wives."

"And yes, it's true, most of the media would like to see us mud wrestle, including [her husband] Evan [Spiegel], but we are here to lead by love because Miranda is love," she continued. "And as a lot of you know, love comes in many family iterations."

Stating that she is "proud to be family with a woman who is living her truth every day with grace and beauty," Perry then said that Kerr is "dedicated to her three beautiful boys, her partner, and that smoking hot bod."

"I'm so grateful for our modern blended family. It's like I gained another sister, one with whom I usually sidebar from the main family chat and agree with," she concluded.

Perry opened up about her family in a chat with PEOPLE a year ago, revealing that her daughter Daisy is just like her famous parents.

"Daisy is great," Perry exclusively told PEOPLE. "She is a combination of both me and her father, which we are fearless with lots of chutzpah and just big characters. So the combination of us both is definitely coming out."

"It's amazing to see everything new again through a toddler's eyes," the mother of one added.
