BRAD Pitt has been giving parenting tips to actor Vince Vaughn.

According to American tabloid the National Enquirer, the pair — who have been good friends since appearing in 2005 movie Mr. & Mrs. Smith together — have been talking about fatherhood since Vaughn welcomed daughter Locklyn Kyla with his wife Kyla Weber in December.

Brad raises six children with partner Angelina Jolie.

“Vince phoned to say he was nervous, and Brad told him, ‘You’d better learn to go with the flow — and forget about sleeping for the next year’,” a source revealed.

The two stars were on the phone for around 30 minutes, during which Vince gushed about his newborn daughter.

Meanwhile, Pitt has left Jolie alone in Los Angeles to jet to France to oversee extensive renovation work on their $70 million mansion.

The Hollywood star — who flew to Paris last Wednesday — obtained a building permit in 2009 to make huge changes to the 35-bedroom Chateau Miraval estate in Provence, which already boasts his-and-hers gyms, a Jacuzzi, sauna, billiards room and huge banqueting suite.

Now the architecture enthusiast is hoping to give the mansion a more “contemporary feel” adding hot tubs, steam rooms, a spa, a new gym, a larger wine cellar and a motorcycle track.

The high-profile couple — who have six children, Maddox, nine, Pax, seven, Zahara, five, Shiloh, four, and two-year-old twins Knox and Vivienne — are also said to be planning a complete overhaul of their security system adding a surveillance center, spy cameras, alarms, and infra-red sensors.

The mansion is surrounded by a dense forest, giving the couple and their children privacy, and the grounds also boast more than 20 fountains, olive trees and a lake.

Upon submission, Brad’s plans for the estate were welcomed by the mayor of the nearby town of Correns, who promised a civic reception to “honor” the famous family to the area.

“The application has been received for widespread work on their new house, and we are delighted that they will be here more permanently,” he said. “They are a wonderful couple with beautiful children and we will hold a civic reception to honor them.”
