Watch Sam Smith on Carpool Karaoke

From ELLE

Four-time Grammy winner Sam Smith was the latest celebrity to appear on James Corden's Carpool Karaoke, and this particular episode came with an extra surprise (or four).

The ride started off like all the others, with the two taking on some of Smith's best hits, including "I'm Not the Only One," "Money on My Mind," and "Stay With Me." They also sang "Lay Me Down," and Smith revealed he was still working in a bar when Corden first tweeted about the song.

But the real magic came when Smith began talking about his love for Fifth Harmony. When he listens to them, he says, "I feel free, I feel alive, I feel like the woman in me is on fire. 'Work From Home' I listen to every time before I go out. I think it’s my wedding song. I want to walk down the aisle to it in heels." So naturally, the two started singing "Work From Home," up until Corden said he thought the song could be elevated a bit...
