Luna was born weighing 6 pounds, 11 ounces, and already has a healthy head of hair. Teigen writes, “She’s here! Luna Simone Stephens, we are so in love with you! And sleepy. Very sleepy.”

“Our new love is here!” Legend tweeted. “We couldn’t be happier!”

The couple had been trying to conceive, but “it was not an easy road having a baby,” a source told E!, adding that the trials have made Luna’s birth that much more of a blessing.
