Lady Gaga appears in a hilarious Carpool Karaoke!
Of all the stars to appear on James Corden's 'Carpool Karaoke'... we were probably most excited about this one!
Lady Gaga joined the likes of Justin Bieber, One Direction and Adele to accompany James on his way to work, we just couldn't wait to see what outfit she would turn up in!
But, it was James Corden who had us all talking about his costumes... and that's because he changed into some of Gaga's famous pieces!
Yup, including the meat dress!
The pair sang Lady Gaga's many hits in one of the BEST Carpool Karaokes to date!
