Jennifer Hudson and James Corden performed a duet featuring public domain songs on "The Late Late Show."
They began their mix of songs when she answered back saying, "I love to take a bath, light some candles and I like to sing 'Skip to My Lou.'"
"No no, no, we don't let it go," Corden said. "We cannot do that. That is definitely not a public domain. That is an insanely expensive song."
"Sorry, your right," the former "American Idol" contestant responded.
The singer and the host concluded with "Happy."
