Izzy named her baby Addie!

Katherine Heigl and husband Josh Kelley have been very quiet about their recently adopted daughter. But now, a rep for the actress, 33, and singer, 32, tells Us Weekly what they've named their bundle of joy: Adalaide Marie Hope Kelley.

Born and adopted domestically, little Adalaide has a big sister in Naleigh, the couple's older daughter, whom they adopted in South Korea back in 2009.

The newly expanded family stepped out for Mother's Day on Sunday in Beverly Hills, with Adalaide covered up with a blanket in a baby carrier.

"Everyone is doing great!" a source tells Us.

"Josh and I started talking about [adoption] before we were even engaged," One for the Money star Heigl said in February of her hubby of five years. "My sister Meg is Korean, and my parents adopted her three years before I was born. I wanted my own family to resemble the one I came from, so I always knew I wanted to adopt from Korea."
