Now this is music to John Legend's ears.
The Grammy winner shared a family video showing his and wife Chrissy Teigen's daughter Esti Maxine Stephens saying one of her first words on Instagram Aug. 13, the day she turned 7 months old.
"What's my name?" John asks his baby girl, while Chrissy adds, "What's daddy's name? Dada?" Esti then repeats, "Dada."
"We got it on tape, baby!" the proud dad exclaims. "Caught on tape!"
Amid the excitement, little Esti started crying. "DADA!" John captioned the video. "Then I got too excited and scared her."
Also seen in the video: Chrissy cuddling the couple's fourth and youngest child, son Wren Alexander Stephens, who was born via surrogate in mid-June.
John and the Chrissy's Court star are also parents to daughter Luna Simone Stephens, 7, and son Miles Theodore Stephens, 5.
The family celebrated another milestone Aug. 12. John shared an Instagram Stories clip of himself and Luna singing "Happy Birthday" to commemorate the 10th anniversary of the release of his hit single "All of Me."
The singer had dedicated the song to Chrissy, who stars in its music video, which includes footage from the couple's 2013 wedding.
The group recently vacationed together as a family of six for the first time.
John shared new pics from their tropical getaway on his Instagram Aug. 13, writing, "Grateful for the quality time with my babies."
