Eccentric singer drives Corden Gaga in Carpool Karaoke
Lady Gaga gave James Corden a fright as she took to the wheel during his chat show's popular Carpool Karaoke segment.
The singer, who passed her driving test a few months ago, was offered the chance to swap seats with the British TV presenter on his commute.
Unsure, she struggled to set herself up and admitted she "can't see very well".
Instructing her to pull away, Corden asked if she had learnt any hand signals for driving in New York, to which she put her middle finger up.
Putting on a helmet as the car lurched forward, he joked: "I don't know if I feel safe in this environment."
Lady Gaga also admitted that her father "cried" when she finally got her licence at the age of 30.
During the 15-minute piece, the eccentric star and Corden sang some of her biggest hits together, including Bad Romance, Poker Face and Edge Of Glory.
While driving around Los Angeles together, they also belted out tracks from her new album Joanne - Perfect Illusion and Million Reasons.
Lady Gaga - real name Stefani Joanne Angelina Germanotta - discussed her collection of "at least 400 pieces" of Michael Jackson's clothes, as well as her forthcoming Super Bowl half-time concert next year.
Corden asked if Jackson's clothes smell and probed the singer over the authenticity of the items before joking that he had been conned before when buying every member of boy band O-Town's T-shirts.
Lady Gaga and Corden also jokingly re-enacted the moment she was offered the Super Bowl gig, with the comic taking on the role of "Dave from the NFL".
More humorous moments came when the host of The Late Late Show donned some of Lady Gaga's most famous costumes, including the yellow caution tape from her Telephone music video and the meat dress she wore to the 2010 MTV Video Music Awards.
Lady Gaga explained her unique style mantra, saying: "The point is to be unfashionable."
Following the broadcast of Carpool Karaoke, The Late Late Show's executive producer Ben Winston tweeted: "This one's special. We've wanted this carpool since we started the show.
"It is all we hoped it would be."
Previous star guests in Corden's car include US First Lady Michelle Obama, Britney Spears, Adele, One Direction and Stevie Wonder.
