John Legend opened up to ET about his daughter's communication skills just last week.
Chrissy Teigen took a break from livetweeting President Donald J. Trump's Inauguration Day for a very special cause.
The 31-year-old model took to Twitter on Friday to share an adorable video of her daughter, Luna, crawling around and waving "Hi" to the camera.

ET caught up with Luna's dad, John Legend, at the TCAs last Friday, where he said that he considers "Hi" his daughter's first word.
"I feel like she already said her first word which is, 'Hi,' because I feel like she's aware she's saying it, and she waves when she says it, so I feel like that's her first official word," he said of the 9-month-old. "It's hard to say [who I see more of in her]… When she starts talking, we'll start to know who she is."
