Nancy Meyers is looking back at her decades of collaborations with Diane Keaton and noting that the past 48 hours have not been easy since the Oscar-winning actress died on Saturday.

While praising Keaton as a performer, Meyers, who wrote Baby Boom and the Father of the Bride films and wrote and directed Somethings Gotta Give, looked back on their close working relationship.

As a woman, I lost a friend of almost 40 years at times over those years, she felt like a sister because we shared so many truly memorable experiences, she wrote in part on Instagram Monday. As a filmmaker, Ive lost a connection with an actress that one can only dream of. She added, We all search for that someone who really gets us, right? Well, with Diane, I believe we mutually had that. I always felt she really got me so writing for her made me better because I felt so secure in her hands.

Though, she clarified, it wasnt just that Keaton could be funny or vulnerable in her films, Keaton did it in projects with Woody Allen, Warren Beatty (Reds) and others that she worked with.

Diane did exactly the same for them because that is what she does. She goes deep, Meyers wrote. And I know those who have worked with her know what I know she made everything better.

After offering some insight into Keatons characters crying scenes in Somethings Gotta Give and how shed sometimes spin in a kind of goofy circle before a take to purposely get herself off balance or whatever she needed to shed so she could be in the moment, Meyers called her late friend fearless.

In closing, Meyers wrote, She was like nobody ever, she was born to be a movie star, her laugh could make your day and for me, knowing her and working with her changed my life. Thank you Di. Ill miss you forever.

Keaton died Saturday at the age of 79, according to a statement obtained by People, as TMZ reported that an ambulance arrived at her home and took her to a hospital shortly after 8 a.m.

Keaton won the best actress Oscar for her role as the titular character in Annie Hall and was nominated for the award three more times, including for 2003s Somethings Gotta Give, in which she starred as a playwright who becomes involved with a womanizer played by Jack Nicholson.

Keatons Father of the Bride co-stars Steve Martin and Kimberly Williams-Paisley previously paid tribute to the late actress, with Martin sharing an interview in which she jokingly responds to friend and Father of the Bride co-star Martin Short asking whos sexier, him or Martin, by saying theyre both idiots.

Williams-Paisley, who had a breakthrough role as the bride in the 1991 film and its 1995 sequel, said of her onscreen mom, Diane, working with you will always be one of the highlights of my life. You are one of a kind, and it was thrilling to be in your orbit for a time. Thank you for your kindness, your generosity, your talent, and above all, your laughter.
