The actress has confirmed to WENN she'll exchange vows with fiance Devin Lucien next month.

"We're a month out, officially," she told the outlet at a Los Angeles screening of her new film Po. "It's (wedding) in Big Sur (California), because it’s close enough, and it feels like a different part of the world from Los Angeles."

And she's still reeling from her DJ fiance's romantic proposal in Paris, France last May (15).

"He first told me he loved me a couple of years before that in New Orleans," the 31-year-old gushes, "so, while we were in Paris, he looked up a New Orleans chef... we went to dinner, and he proposed to me. It was very sweet."

But Kaitlin has a very important film to promote before she ties the knot - Po tackles autism and the actress reveals the neurodevelopmental disorder really hit home for her recently.

"Someone in my family was diagnosed a few months ago," she added. "It’s painful because we didn't know for so long... but now we can get him the help that he needs.

"I hope that the film will show people who are affected by autism that there’s awareness. There are people that are in the film industry that are writing stories about them, and wanting to share their plights. There is hope and they’re not alone."

Po will begin its festival run at the Panama Film festival on Sunday (10Apr16).
