Katherine Heigl’s personal and professional lives collided while making her new romantic comedy “Life as We Know It.”

“I literally became a mother four days before filming began so the whole process of filming and my personal life it’s all on camera,” the actress, who adopted her daughter Naleigh with husband Josh Kelley in September 2009, told Access Hollywood Thursday night at the film’s New York premiere.

“I couldn’t get (a chance) to set (up) and sort of divorce myself in order to become someone… I really couldn’t even attempt it because it was so… my brain was in 14,000 places at once, and so what you see is what you get with me,” she continued.

The 31-year-old actress told Access this movie, which co-stars Josh Duhamel, holds a special place in her long list of credits.

“I’m really proud of this movie. It’s probably my favorite film I’ve done to date,” she explained. “It’s just the perfect combination of romance and comedy and heart. I think people want a real story these days, the fantasy, the wish fulfillment is fun and I always love those movies and hope to always get to do them… it was grounded in a lot of humanity, these people are real people.”

“Life as We Know It” hits theaters on October 8.
