Jennifer Garner is happy to get rid of 'child' Ben Affleck

Jennifer Garner is excited she does not have to worry about ex-husband Ben Affleck.

The mother-of-three is elated by the recent nuptials of the director and is 'thrilled' to relay herself off his responsibility.

“I’m sure she’s thrilled to get rid of her fourth child,” a source told Page Six.

Garner, who was not invited to the nuptials, sent children Violet, 16; Seraphina, 13; and Samuel, 10, to see their father marry JLo in Georgia.

“Jen has always approached things the same, no matter who Ben has been with,” said one insider. “They have kids together — so if he has another episode, or falls off the wagon, it would be her problem.”

“Jen is a great mother, she has really mothered those kids — and it’s great that she doesn’t have to have a fourth child anymore," they added.
