Ring, ring, ring, ring, ring, ring, ring, bananaphone!

This is too adorable! If you haven't already, watch the video (above) of Reese Witherspoon having some "fun with fruit" and Raffi's hit song "Bananaphone" (1994) with her almost-three-year-old son, Tennessee—and the latest It app of the moment, Dubsmash, which lets you create mini selfie-lip-syncing vids.

"Good morning! ," she captions the adorable video, "Pick up the banana phone! #toddlertime #funwithfruit"

Tennessee has been showing up more on Reese's Instagram. Check him out sending his half-brother, Deacon Phillippe (Reese's son with Ryan Phillippe), 11, off to school.

Oy, so sweet. Reese is also mom to Ava Phillippe, 15,

Ring, ring, ring, ring, ring, ring, ring, bananaphone! Uh-oh, I have that song in my head now. Didn't foresee that.
