Swizz Beatz reveals that his five-year-old son lent his production assistance on Kendrick Lamar’s untitled unmastered album.

With the release of Kendrick Lamar’s untitled unmastered album, Swizz Beatz had what he described as a “best dad moment.” The producer’s best dad moment stemmed from his son, Egypt producing “2014 – 2016,” a track featured on Kendrick’s new, surprise album.

Swizz shared the moment on Instagram, posting a picture of a screen capture of the song, and adding the following caption:

“This is the best Dad moment everrrrr!!! Congrats to my son Egypt for producing his 1st track on this amazing Kendrick Album he’s only 5yrs old wowwwwwww @aliciakeys look at our lil guy baby #blessingsonblessings thx #Kendrick for investing in the future !!! Track 7”

The beatsmith also uploaded a video of Egypt making the beat for the song. In the video, the five-year-old can be seen playing the piano while the song’s beat plays in the background.

In the caption to the video, Swizz explains that his son had “no help on the beat.”
