It’s a boy! Jennifer Garner and Ben Affleck have welcomed a son to their family, a source confirmed to People. This is the celebrity couple’s third child, and the little guy will no doubt be well loved by his sisters, Violet, 6, and Seraphina, 3. Back in September, Garner told Ellen DeGeneres that having a boy “would be so weird” but also “cool and different.” The baby’s sex may have come as a surprise to the rest of the world, but Garner told Jay Leno in January that she and Affleck knew what they were having. Mum's still the word on the baby’s name for now.
