Just when you think James Corden's guests can't get better on Carpool Karaoke, he pulls out another few top celebrities to add to his list.

This time James is joined by 'Too Good At Goodbyes' singer Sam Smith and American girl group Fifth Harmony for an amazing rendition of 'Work from Home'.

First to join James in the car is Sam Smith who starts by singing his fabulous current single 'Too Good At Goodbyes' with the show's host. The pair then go on to talk about how things have changed since they first became famous.

Sam Smith reveals, "my plan is to keep my weight down for another 10 years and then I'm going to live in kaftans", to which James breaks out in laughter.

The pair then start singing some of Sam's most iconic songs including 'I'm Not the Only One' and 'Money on my Mind'.

After belting out the hits Sam then admits that he had missed school to see a Lady Gaga concert and got in trouble for it! He told James how he had forged a letter from his dad with a terrible excuse and unfortunately he was found out. He had written the letter on the computer at school and left it logged in! #FAIL

The topic of conversation then took a strange turn as Sam started to talk about his plan to have a 'funeral' for his single life before he gets married to a future husband.

The 25-year-old singer then admitted to James that he is a massive Fifth Harmony fan and the pair started to sing their hit single 'Work from Home'. Less than a minute into the song James decides to stop the car and make a call, this when the members of Fifth Harmony make a surprise appearance and Sam gets all embarrassed!

Watch the full video below when Sam Smith sings 'Work from Home' with the girl group:
