So, Katherine Heigl and husband, Josh Kelley, have officially arrived back home with the newest addition to their family–their newly adopted baby girl. A snitch spills to RadarOnline.com, “They are truly a happy, happy family.”

At the moment, Katherine is off from her gig on Grey’s Anatomy and spending time with her little one. Her friends and co-stars (former and present), T.R. Knight and a super-pregnant Ellen Pompeo, have been dropping by to pay a visit to the couple and meet their new daughter.

Next week, Heigl will return to work filming her film Life As We Know It. As she tells Ellen DeGeneres, her decision to adopt was made even before she and her hubby got hitched. “So about a year ago is when we said, ‘OK, let’s start the process,’ and the process is intense.”

From the smiles on the faces of both Knight and Pompeo, it looks as if all the effort has paid off. In fact, is that a little drool spot we spy on T.R.’s shoulder? Too cute.
