Is there trouble in paradise already for newlyweds Brad Pitt and Angelina Jolie?

The A-List couple has only been married for three months, but some sources reveal that Brangelina are already going through marital problems.

According to Woman's Day, Pitt and Jolie "were witnessed having a blazing argument on their Sydney hotel balcony." The two were in Australia for the premiere of World War II film "Unbroken," which Jolie directed in New South Wales and Queensland, the outlet added. They were reportedly joined by their twins, Vivienne and Knox.

"Brad, 50, downed a Crown Lager at the early hour of 10am and the pair were both seen clutching cigarettes as their intense discussion raged on," Woman's Day reported. The entertainment site's sources said Jolie was obviously upset during the apparent argument with Pitt, which "could be down to Ange's hectic workload in the past year." Pitt was photographed "throwing his arms up in a frustrated manner."

Later on in the evening, the couple graced the red carpet premiere of "Unbroken" at Sydney's State Theatre. Woman's Day noted that they arrived in a black Land Rover but something's not right, even if they were all smiles for the camera. The fans reportedly sensed the friction between them.

"Brad busied himself signing autographs, while Ange focused on speaking to the assembled media on the other side of the road," the news outlet further reported. Their brief hug and kiss looked "stiff" while photographers reportedly had a hard time snapping a picture of the two because the cast of the movie were "strategically placed between them."

Jolie Plans to Become a Better Wife

Amid all the divorce rumors, Jolie said that she's trying to please her husband more. In an interview with "Today" on Tuesday, the actress opened up to Tom Brokaw about her marriage to Pitt.

"I think we have more moments where I'll say, 'I'm going to be a better wife. I'm going to cook.' And he says, 'Oh, honey. Just know what you're good at. Know what you're not.' " she said. "But I do this, 'No, no, no! I'm gonna get this wife thing down.' But he knows my limitations and where I'm a good wife and a good mom," Jolie revealed, as quoted by E! Online.

The couple married on August 23 of this year after 10 years of being together. The two have six kids -- Maddox, Pax, Zahara, Shiloh, Knox and Vivienne.
