Ring, Ring! It's Reese Witherspoon and Son Tennessee on the Bananaphone

Pick up your banana – it’s Reese Witherspoon and Tennessee calling!

The Oscar winner goofed around with her youngest child on Sunday, recording their own video on the popular app Dubsmash.

Lip-syncing along to children’s performer Raffi’s 1994 tune “Bananaphone,” Witherspoon and Tennessee, who turns 3 on Sept. 27, took turns mouthing the cute lyrics to the song.

At first, Tennessee struggled to match the quick-paced lyrics while holding a ripe banana to his ear, but by the second verse, the toddler was a natural.

“Bananaphone,” he fake-crooned with gusto.

“Good morning!” Witherspoon captioned the video, adding a sun emojii. “Pick up the banana phone!”

The actress, who shares Tennessee with husband Jim Toth, also has two older children, Ava, 15, and Deacon, 12, with ex Ryan Phillippe.

Witherspoon had previously opened up about the struggle to balance her career and motherhood.

“There are some sacrifices you make, and it hurts your heart sometimes, but my kids tell me they’re proud of what I’ve accomplished, and that just means everything,” she told Southern Living. “I grew up with a working mom, and I have so much respect for the things she did as a nurse and a teacher. I would never begrudge her that.”
