"I heard your baby's named after her grandmother?" Washington asked Kimmel. "Mine is too, named after my grandmother."
"We should swap them and see if our families notice," joked Kimmel. "Just for a few days."
Washington, 37, and her husband, Nnamdi Asomugha, 33, welcomed their daughter, Isabelle, in April. During her pregnancy, Kimmel, a "good friend," pampered the actress with a shipment of barbecue from La Barbecue in Austin, Texas.
"There's nothing more kind to do for a pregnant lady than [sending her] a box full of frozen deliciousness," gushed Washington of the gesture. "It was amazing."
