NEW YORK • Already famous for her toned arms, we now know Michelle Obama has a voice to match.

The First Lady toured the White House grounds with Late Late Show television host and British comedian James Corden for his "Carpool Karaoke" segment, belting out hits like Stevie Wonder's Signed, Sealed, Delivered I'm Yours and Beyonce's Single Ladies.

The sing-along session - a recurring bit on the talk show that has featured stars such as Justin Bieber, Adele and Elton John - included banter about the Obama family's Secret Service code names, Snapchat and life after the White House.

"Are you not going to miss, like, 24-hour room service?" Mr Corden asked. "Just calling down at 3am, 'I want a grilled cheese and a milkshake?'" Mrs Obama replied that freedom rediscovered will outweigh the loss of presidential luxury.

Mrs Obama also noted her ride with Mr Corden was only the second time in nearly eight years that she had the chance to "rock out" in a car, the first being when she taught her daughter Malia how to drive.

Mrs Obama also highlighted her global girls' education campaign by singing the initiative's theme song This Is For My Girls, which features pop stars Kelly Rowland, Janelle Monae and Missy Elliott.
