Michelle Obama channels inner Beyonce for TV sketch

Already famous for her toned arms, we now know Michelle Obama has pipes 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 late-night talk show that's featured stars like 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?" Corden asked. "Just calling down at 3:00 am, 'I want a grilled cheese and a milkshake?'" Obama replied that freedom rediscovered will outweigh the loss of presidential luxury. "I can make a mean grilled cheese sandwich," she added. Obama also noted that her ride with Corden was only the second time in nearly eight years that she's had the chance to "rock out" in a car, the first being when she taught her daughter Malia how to drive. 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. Elliot even dropped by the carpool to help the first lady reprise the rapper's 2001 classic "Get Ur Freak On." In light of the recent Melania Trump plagiarism row, it's perhaps no coincidence that the rap Obama chose included the lyrics: "Ain't no stoppin' me/Copywritten so, don't copy me."
