Brad Pitt is urging pregnant lover Angelina Jolie to quit her hectic charity schedule until after their baby is born in the summer.

At over four months pregnant, Angelina, 30, is still as busy as ever with her movie The Good Shepherd and demanding timetable as a goodwill ambassador.

And although he supports her, sources say that Brad, 42, has begged Angelina to take it easy — especially since she’s apparently been sick since the beginning of her pregnancy.

The Tomb Raider beauty reportedly suffered a string of dizzy spells and even fainted on the set of her new thriller.

“Brad’s told Angelina to relax and put her charitable commitments on hold until after the birth,” said an insider.

Another source, who spends time with Brad at Santa Monica Airport, Calif., where the actor takes flying lessons, said: “Brad wants to literally ground her for the rest of the pregnancy. Whether it be as a pilot or as a passenger, he fears for her and the baby’s safety and wants her to rest during the all-important second trimester.”
