Kate Hudson and Kathryn Hahn are back onscreen together.

At the Los Angeles premiere of their new film Glass Onion: A Knives Out Mystery Monday, Hudson, 43, told The Hollywood Reporter that reuniting with her How to Lose a Guy in 10 Days costar Hahn, 49, "was the best."

"We were really close for many years and then as it goes, kids, marriage, other kids, other marriages — for me; she's still in hers!" Hudson said of Hahn at the premiere of the Knives Out sequel, written and directed by Rian Johnson.

Hudson mentioned that 2003's How to Lose a Guy in 10 Days is approaching its 20th anniversary in January, making her reunion with Hahn for Glass Onion all the more timely.

"It turned into years where we hadn't seen each other and when I saw her, when I was reunited with her on this movie, it was like we'd never left," the actress told THR. "I feel like we are soul sisters. It's the best."
