Added a Hollywood insider: "Channing likes that she is independent and outspoken as well as bright."

Kravitz is a mainstay on The Met red carpet, having attended the past few years after making her debut in 2008, walking the carpet with her famous parents, Lenny Kravitz and Lisa Bonet, in 2015 and at the last Met Gala in 2019, in Saint Laurent.

Tatum attended once back in 2007 for the Poiret: King of Fashion exhibition.

The two connected after Kravitz approached the Magic Mike actor to be in her directorial debut, Pussy Island, which she has described as a "genre thriller" that will explore gender politics and is set to begin production early next year.

"Chan was my first choice, the one I thought of when I wrote this character," Kravitz told Deadline. "I just knew from Magic Mike and his live shows, I got the sense he's a true feminist and I wanted to collaborate with someone who was clearly interested in exploring this subject matter."
