I'd tweet thanks to Angelina Jolie, but she's not on Twitter. She was warm and fun in our interview for @peoplemag. http://t.co/eoEDKnSDkV

I'm preemptively negating the inevitable "Is Angelina pregnant" stories that surface this time each year. @peoplemag http://t.co/knkgR2EqCG

When asked in this week's cover story if she planned to have more kids, the actress and director, 39, tells PEOPLE exclusively, "Not at the moment, no."
Still, the Oscar winner admits that decision isn't final.
"Something could change tomorrow," she says, "so I don't know."
Jolie and her husband, Brad Pitt, are the parents of six: Maddox, 13, Pax, 11, Zahara, 9, Shiloh, 8, and 6-year-old twins Knox and Vivienne.
This summer, Jolie put Maddox to work as an assistant on the set of By the Sea, the upcoming drama she directed and costars in with Pitt.
"We spend so much time at home that the film aspect is a fun part of our lives," Jolie says of her children. "They come to the sets – but they also do so many other things with us."
The kids travel on United Nations trips with Jolie, build houses with Pitt for his Make It Right foundation and even helped plan their parents' wedding last August.
Despite her reservations about getting married, Jolie was "extremely moved" by how happy it made her kids, especially since they'd been constantly asking when the two would finally tie the knot.
"I want to have a strong marriage," Jolie says, "[and] I want to raise my children well."

"My son [Maddox] became a teenager," Jolie, 39, tells PEOPLE. "That was a marker in my year."
In this week's exclusive cover story, the actress and director looks back at 2014 and reflects on how much her life has changed since her 20s, admitting she never thought she could be this happy when she was growing up.
"More than anything, like any mom, I'm just happy the kids are healthy," Jolie says. "I married their dad. My health is good."
Jolie talks about how her six kids are growing up – and how they played a big role in the couple's August nuptials, acting as wedding planners for the big day.
"They did a really good job!" Jolie raves about the wedding, held at their estate in France. "The eight of us celebrated, and Brad and I committed our lives to the children."
The director of the World War II drama Unbroken, out Dec. 25, also discusses her future and says she'll do just a few more acting jobs before making a permanent move behind the camera.
"I've loved being an actor, but I'm happier shining a light on other actors," she says.
The star can even see herself getting into politics in the future. "I do want to make change, so I'm open to whatever role that may take," she says.
Jolie tackled several major projects in 2014, including executive-producing and playing the lead role in Disney's $700 million hit Maleficent, hosting a summit to fight sexual violence and taking on what she called "the hardest thing I've ever done" professionally: directing Unbroken, which chronicles the life of Olympic runner and prisoner of war Louis Zamperini.
The challenge of the biopic, says Jolie: "How do you get this man's huge life into one film?"
The movie played a role in another one of Jolie's notable memories of this year: "Sitting with Louie in the hospital, showing him Unbroken, that was probably one of the greatest moments of my life," she says. Zamperini died in July at age 97.
Jolie says the war hero taught her how to rise to a challenge – and another important lesson.
"We're not alone in the world," she says. "I don't know if there's a name for that – religion or faith – just that there's something greater than all of us, and it's uniting and beautiful."

The older her children get, the more they realize their parents are famous.
"Brad and I don't know any other way. We spend so much time at home that the film aspect is a fun part of our lives, but it's a small part. We don't shield the kids from it—they come to the sets—but they also do so many other things with us," the Salt star said. "They travel on my United Nations trips. They work with Brad and talk to him about building houses [for his Make It Right Foundation]." Laughingly, Jolie said, "If you ask any of the kids about us, I feel like they'd say, 'Let's talk about how Mommy and Daddy are so uncool. That Daddy makes better pancakes than Mommy.' That's about their level of interest."
Jolie calls herself "old-school" (she doesn't use social media), although she understands that her kids are growing up in a more technologically advanced era than she did. As such, she's made using the internet as safe as possible. "For the kids, we have someone who monitors that," she explained. "It's so beyond what we understand. We wouldn't even know what to look for. It's a scary new world. I can only imagine the trouble I would've gotten into. I got in enough trouble. It just would have been very documented."
