Reese Witherspoon is a proud mama. In her latest Instagram post, she can be seen dancing with excitement to her son Deacon's new single "Long Run." Witherspoon is in full doting mom mode and even came up with the idea to create a Tik Tok dance for his song. Her son was not impressed with the idea.

Witherspoon posted, "When your kid has his first single... you gotta dance! Nina Nesbitt, who collaborated on the track, said that she wanted to see the dance. Eva Longoria and Octavia Spencer also chimed in on Witherspoon's post in agreement.

Deacon, who goes by his first name only as a musical artist, is not actually singing on the track: Rather, he is starting his career as a music producer. He collaborated with Scottish singer Nina Nesbitt, who's known for her hit single "Stay Out." Deacon is also credited as one of the composers for the song.

The song is a pop dance track that starts off with light strings before Nesbitt begins singing. Witherspoon's previous Instagram post states "It's the perfect summer bop with a sick beat and dope drops (is that what the kids say?!)." The track is easy on the ears and is pop-radio-friendly.
