Sam Smith is the latest celebrity to take a ride with James Corden for Carpool Karaoke with a surprise appearance by Fifth Harmony.

Smith is the latest on a long-list of stars to hitch a lift with Corden on his daily commute around LA.

During their journey Smith and Corden belt out a number of the award-winning singer's chart-topping songs including Stay with Me and I'm Not the Only One.

However, the best part comes when Smith declares his love for US girl group Fifth Harmony, revealing he wants to "walk down the aisle in heels" to their hit Work from Home.

Smith squeals with delight and surprise when the ladies then jump into the back of the car and exclaims: "I'm actually shaking! Oh my god this is my dream!"
