The "My Life Would Suck Without You" hitmaker, who has three-year-old daughter River Rose and 19-month-old son Remington Alexander with husband Brandon Blackstock, said she recently enjoyed a "magnificent" double date at Gwen's house.
"You know, we've already (double dated) at her house, which is magnificent. And her family was there. It's a real testament of how she's such an awesome girl - it's because of her family. Her family was super rad and down to earth. They're really, really cool," Clarkson said, according to Femalefirst.
"Her house is insane. I walked in and I literally felt like the 'Pretty Woman' scene when you don't belong in the store. I was like, 'I have a nice house,' but [with] hers, I was like, 'Damn!'" she added.
