Chrissy Teigen and John Legend became parents in April when their daughter, Luna Simone, was born, and on Friday, Chrissy celebrated the six-month milestone by taking her little girl to the park for the first time. In a Boomerang video posted to Instagram, Chrissy holds on to Luna as they go down a slide. The model and Cravings author captioned the clip, "I can't believe you have been making me laugh and smile and extremely sleepy for 6 months now! First trip to the park. Best NYC stroll day ever. I love you, my Lu!" So sweet.
