Clarkson and Corden got directly down to business, busting into the artist's achievement 2004 hit "Since U Been Gone", which segued directly into her most recent crush, the heartfelt, "Love So Soft" from Kelly's Meaning of Life collection, finish with that executioner high note.
But when you combine the two, you get something pretty unbelievable. "I think it's hard", she responded, "because I work a lot and I'm a mom, but we try".
Before her husband surprised her, Kelly confessed she doesn't get to spend a lot of with her husband. "Is this an intervention?" The set-up wasn't exactly natural, prompting Blackstock to exclaim, "I feel like we're making a porn!" In addition to fitting in a date with her husband Brandon Blackstock. By the looks of things, Corden spared no expense, and set up the husband and wife with champagne, chocolate-covered strawberries and even a violinist.
Now the couple have four kids between them - Brandon's daughter Savannah, 16, and son Seth, 10, and their own children, River Rose, three, and Remington, 19 months. "It's supposed to be a romantic date night!"
Sometimes we just enjoy watching "Carpool Karaoke" and sometimes we seethe with jealousy that James Corden of all people got to share a vehicle and sing along with the celebrity in question.
