Reese Witherspoon is one proud mama after her son, Deacon Phillippe, released his first single and she doesn’t care who knows it.

In a cute video posted on her Instagram captioned, “When your kid has his first single… you gotta dance!”, Witherspoon loved hearing Deacon’s song but then comes up with an idea.

“Deacon, I should make up a TikTok dance to the song,” Witherspoon said as she got up to dance.

A very embarrassed Deacon groaned, “Mom, no.”
