Jennifer Garner on 'Ellen': Ben Affleck is "Wonder Sperm" Kind of Guy, Wants More Kids [VIDEO]

Actress Jennifer Garner stopped by the "Ellen DeGeneres Show" on Thursday, happy to admit that her husband Ben Affleck is a "wonder sperm" kind of guy who would love to have more kids one day (adding to the couple's current number of three). But looks like the "13 Going on 30" star is content right now adjusting to life with an infant son, which she suggests is a whole lot different from raising two little girls.

"I mean, [my daughters] didn't pee in my eye," the 40-year-old starlet joked to the daytime television talk show host. Garner goes on to insist that 7-month-old Samuel is "really, really, really sweet" and is a great addition to the family which already includes six-year-old Violet and 3-year-old Seraphina.

The "Butter" star goes on to describe how motherhood is with three boisterous children running around, "I don't know if it's because he's a boy. I don't know if it's because he's my third and I forget that I have him. You're just dealing with two and then you think, 'I swear I put a baby down somewhere.' And you kind of walk through the house, 'There you are!' and he's just happy as can be.'"

Still, Garner doesn't blame Affleck for having such "wonder sperm," - "Come on, I mean, just have a look at him!" she exclaimed. 

Garner also gushes over the kids' 40-year-old daddy (which is maybe why he wouldn't mind having more babies?). Affleck is supposedly great with the two girls, and even enjoys taking part in numerous tea parties - "He can do it without using any energy at all. He can sit there and be almost asleep and they think they're having an incredible game with him. It's skill," Garner said.

Along with raising three young children, the Hollywood couple is busy at work - Affleck is currently filming a movie due out 2013 ("Runner, Runner"), and Garner is out promoting of her upcoming October comedy "Butter."
