Amanda Seyfried and her family are big fans of Halloween!

In an exclusive conversation with PEOPLE about her partnership with Synchrony’s CareCredit and Pets Best insurance, the actress, 38, also opens up about her love of all things scary and how she celebrates spooky season with her family.

“Halloween’s huge in our house. We go all out,” Seyfried says, referring to herself, husband Thomas Sadoski and their children — daughter Nina, 7, and son Thomas, 4.

“Every year, we have this party, and these local guys who do Christmas lights put in Halloween colors throughout the woods,” she continues. “We have candy, some inflatables, and this year we’re doing fog machines.”

“Then we do our trick-or-treating in the nearest town on actual Halloween,” adds the Jennifer’s Body star.

According to Seyfried, her love of Halloween has been passed down to her two children. “In fact, my daughter just made a haunted house in our playroom the other day,” she tells PEOPLE.

As for what her kids want to go as during the annual fall holiday, the mother of two says of her daughter, “She wants to be this weird clown.”

“She’s wearing a red wig and she wants those teary black [eyes],” the Mamma Mia! and Mean Girls actress continues of her mini-me’s planned attire.

As for her son, Seyfried says he is more laid back in his Halloween plans and has actually requested to rewear an outfit from a past year.

“My son’s a firefighter again,” she says with a laugh of Thomas.
