BRAD'S $650 MILLION PRENUP

After surviving a nasty divorce, Brad Pitt is ready to wed again on one condition

Believe it or not, Brad Pitt turned 60 on Dec. 18. A day later, looking as youthful as ever, the A-lister celebrated the milestone with a laid-back, fourhour dinner with his girlfriend of a year-and-a-half, Ines de Ramon, and about 30 friends in a balloon-filled private room at LA's Mother Wolf restaurant. "He was beaming," says a witness. "He kept Ines close by his side the whole night." He'd like to keep her close for a lot longer than that. "Brad is head-overheels in love with Ines and wants to marry her," says the source. But after enduring seven hellish years at war with Angelina Jolie over every detail of their lives together - including a $350 million battle over his beloved French vineyard, Château Miraval "he isn't taking any chances this time. Brad's going to insist that Ines sign a rock-solid prenup to protect as much as $650 million in his assets and future earnings."
