He’s the host of the four-time Emmy nominated show Billy On The Street, which sees him perform hilarious street interviews with celebrity guests.

And comic Billy Eichner posted one of his most iconic episodes on Monday as he chatted up Mariah Carey.

The 41-year-old took to the streets of New York with the singer to spread some holiday cheer and surprise unsuspecting passerbyers before the 49-year-old saved Christmas.

The first stop saw the duo offer a menorah to a pedestrian if he could finish the lyrics to the Dreidel song.

Mariah confessed she ‘wasn’t looking’ at the lyrics as she sung the popular Jewish song – but there appeared to be some confusion over the last line when the passerbyer said: ‘Dreidel I shall play.’

And while according to online reports that appears to be correct, the five-time Grammy winning artist said it was wrong.

Can he do it? The first stop saw the duo offer a menorah to a pedestrian if he could finish the lyrics to the Dreidel song

Best day ever! Fans were shocked and overwhelmed when they met Mariah on the street

‘It’s Dreidel I will play,’ she proudly said meaning Billy took the menorah off the winner – although he was correct.

‘Goodbye! Wrong! Don’t f**l with Mariah’s Hanukkah lyrics,’ said Billy storming off.

The duo were then greeted by two Swedish tourists to which the mother-of-two surprised fans with her ability to speak the language.

‘Woah! My God! Meryl Streep over here with the accents and the languages.’

Mariah saves the day! ‘Someone help us with the tree, I got Mariah Carey here. Christmas is ruined,’ the Parks and Recreation star yelled. The All I Want For Christmas Is You singer responded: ‘No, no, no, not ever,’ the pair said when they dropped their tree during filming

Billy also got strangers to kiss on the street while holding up some mistletoe.

However all wasn’t smooth sailing after their small tree they were carrying broke, to which the comedian called Christmas over.

‘Someone help us with the tree, I got Mariah Carey here. Christmas is ruined,’ the Parks and Recreation star yelled.

The All I Want For Christmas Is You singer responded: ‘No, no, no, not ever.’

‘This is what happens when a Jew tries to celebrate Christmas,’ he continued.

The duo ended up leaving the broken tree on the street, turning it in to a piece of ‘art’ for those walking by.

Back at the top! The video release comes as Mariah’s Christmas hit song was officially named number one on the Billboard Hot100 charts on Monday morning

When the episode was posted, Billy excitedly captioned on Twitter: ‘IT’S HERE!!! BILLY ON THE STREET with the LEGENDARY @MARIAHCAREY!!! A HOLIDAY GIFT FOR THE WORLD!!!!’
