The 40-year-old star says her close pal did a fabulous job making her directorial debut in 'All We Had' and joked she was incredibly "bossy" with the cast and crew.

She told PEOPLE magazine: "She's amazing. She wasn't bossy, no ... I mean, she's bossy, don't get me wrong, but she was never bossy with me.

"I liked working for her a lot. It's fun to get immediate feedback from your friends about your performance. It's great! It's always fun to have someone come and see what you're doing from a different view. She's a great director. I think she's gonna be fine."

Meanwhile, Katie previously admitted she found it "challenging but rewarding" stepping behind the camera for the first time.

She said: "I was actually on both sides [of the camera]. It was an undertaking, but the movie was produced by Jane Rosenthal and you couldn't ask for a better producer, so I felt very taken care of.

"It was very challenging! But very, very rewarding. Hopefully you just get better every time you do it. That's what I'm hoping for."
