With the whole family in showbiz, Hollywood mom Jada Pinkett Smith says high maintenance isn’t an option in her household.
Pinkett Smith, 37, has been married to funnyman Will Smith for 11 years, and their two kids, 10-year-old Jaden and 8-year-old Willow, already have a few movie credits under their belts. Jaden performed alongside dad in The Pursuit of Happyness, while Willow voiced the character of Baby Gloria in Madagascar: Escape 2 Africa. Fittingly, Pinkett Smith starred as the older version – Gloria.
But Pinkett Smith says her family is simply doing what they love.
“Everybody just enjoys doing what they do,” she says in an exclusive chat with PEOPLE at the London premiere of the Madagascar sequel. “We’re all really happy, so we just do it.”
She adds: “Thank goodness in my family we don’t allow divas.”
Ben Stiller – whose two kids also voice some parts in the new animated film – joined Pinkett Smith and Chris Rock on the red carpet Sunday afternoon. Stiller, 42, says he’s looking forward to Thanksgiving family time and his favorite part of the meal: Turkey.
“I’m just going to be home with the family,” he tells PEOPLE exclusively. “We’ve been doing this world tour [of Madagascar: Escape 2 Africa], so it’ll be nice to be home. I get home the night before Thanksgiving.”
Stiller says actress wife Christine Taylor, 37, is “the big cook.” But everyone, including their kids Ella, 6, and Quinlin, 3, does their part to contribute.
“We just have fun,” he says. “Everybody gets together and has dinner and hangs out.”
