"I've held baby Luna in my arms," Jackson gushed. "She is absolutely beautiful."

Jackson confirmed the new parents are doing well and have returned to their home with Luna. "They’re doing great. They're happy. They're elated," he said. "It's a long time coming. They went through a lot to have this child. They're excited. We're all really blessed to have her a part of all our lives."

So who does little Luna look more like: Mama or Papa?

"Oh my gosh. I'll let them talk about baby Luna," he said. "I think she looks like both of them. She's gorgeous!"

Legend and Teigen announced Luna's arrival to the world on Sunday. "Our new love is here!" the "Glory" singer tweeted. "Luna Simone Stephens, born on Thursday, the 14th. We couldn't be happier!" Stephens is Legend’s real last name.
