The 41-year-old actress finalised her divorce with art consultant Will Kopelman - with whom she has two daughters, four-year-old Olive and Frankie, two - in August this year, and says whilst the former couple are still communicating, it takes thorough planning to make holidays like Halloween run smoothly.

Asked how she makes single parenting work, the '50 First Dates' actress said: "I think plans. Constant plans. We, as a family, have three dates for this Halloween."

And whilst the candy collecting holiday might be aimed at children more than adults, the blonde beauty admits the ghoulish annual festivity is "the best day ever" for her, as she enjoys being "an anonymous parent".

The 'Never Been Kissed' star said: "[Halloween is] like the best day ever. It's the only day that's acceptable and not totally creepy to wear a mask, so God bless Halloween! I love it. I get to be an anonymous parent that night, so I'm into that!"

Despite her love for Halloween and dressing up as something she's not, the 'Ever After' actress says her biggest beauty secret is her ability to be herself, and only wear makeup on special occasions in order to "feel special".

Speaking to ET Online, she said: "I have a motto, 'A smile is better than any lipstick you're ever going to buy.' So if I can be just me every day of my life and have the makeup moment feel special or like I'm carving something out of my time, or I'm making an effort to show someone in a meeting or a dinner that I've made the effort -- it feels special. But every day is not like that."
