Ben Affleck is begging wife Jennifer Garner to get pregnant one more time and give him the son he's desperate for.

The couple has two daughters, Violet, four, and 12-month-old Seraphina, and Affleck is keen for a baby boy to complete the trio.

But Garner is reluctant to abandon the pre-pregnancy figure she worked so hard to achieve.

The actress tells Us Weekly, "Ben would like a boy, but I don't want another baby right now."

And Garner's friends are on her side, one pal telling the star, "You don't want to do that all over again. You worked hard to get your body back."
