Scott Disick wants to dress-up as Batman on Halloween (31.10.14).

However, the reality TV hunk insists he and his long-term girlfriend Kourtney Kardashian, 35, who is pregnant with their third child, only dress-up for the for their son Mason, five, and daughter Penelope, two.

Although, the kids are yet to decide on their costume for the event, which involves pumpkin carving, trick-or-treating and apple bobbing, but Scott believes whatever they choose to wear will be "ridiculous."

Asked what Mason and Penelope are wearing for Halloween, Scott told PEOPLE.com: "Whatever they want. Whatever is exciting them. I'm sure they'll find something ridiculous."

Meanwhile, Scott and Kourtney are currently preparing for the arrival of their third child - believed to be a baby girl - in December and have been busy decorating the new nursery with the help of Mason in their $8.5 million home in Calabasas, California.
