Carpool Karaoke might be the greatest segment on a late night talk show ever. The moment Stevie starts singing to James Corden's wife is priceless.

James Corden does a segment on The Late Late Show called Carpool Karaoke where he drives around with celebrities singing along to their own songs. They are absolutely fantastic. If you've never seen them before, you must watch.

Corden releases a new one each month. His other guests have been Mariah Carey, Jennifer Hudson, Justin Bieber, Iggy Azalea, and Rod Stewart with A$AP Rocky

Stevie Wonder was his latest guest, and one of the big moments from the video is where Stevie calls up Corden's wife to serenade her with his song I Just Called to Say I Love You. But what he actually says is, "I just called to say James loves you," and Corden is wiping tears away by the end of it.

Here's the entire 10-minute video. Stevie sings to Corden's wife around 4:00
