Naturally, her proud parents documented the sweet moment on social media.
“Mommy and daddy posing. Luna stealing the Mariners' bubble gum #LunasFirstTour #Seattle,” Legend captioned one sweet shot in the dugout.
The “All of Me” singer, 38, also posted a photo of himself and Teigen holding up their little girl and the baseball she adorably threw.
“Proud papa #LunasFirstTour,” Legend captioned the shot.
The family is following Legend on his Darkness & Light Tour, and Legend performed in Woodinville, Washington, on June 3 and 4.
The Mariners were thrilled to have the A-list kiddo on their team, tweeting, “Many thanks to @chrissyteigen and @johnlegend for letting Luna throw out our first pitch. It was a heater right down the pipe.”
