Kelly Clarkson recently paid a visit to Gwen Stefani's home on The Summit in Beverly Hills, California and she is quite impressed by the massive pad.

During a new interview, Clarkson opened up about her experience at Stefani's home, admitting that she felt a bit out of place when she first entered the Stefani's home.

"The first time I saw Gwen's house, it's insane!" Clarkson told Entertainment Tonight via a report by The Daily Journal Online on March 13. "I was kind of like 'Pretty Woman' walking in the store, except I didn't look like Julia Roberts, and I was walking in the store and they were like, 'You don't belong here.' "

Stefani's home is currently on the market for $35 million and if she gets that price, she'll be making one heck of a profit. After all, she and her former husband Gavin Rossdale spent just $13 million when they purchased the home over a decade ago.

A report from Hooked on Houses revealed that Jennifer Lopez actually lived in the 7-bedroom, 11-bathroom house before Stefani and Rossdale bought it. The report also revealed that the home boasts a gym, pool, and spa, and the master suite actually includes two bathrooms and two separate closets.

"I felt like I was a good interior decorator, and then I walked into Gwen's house," Clarkson continued.

However, according to Stefani's boyfriend, Blake Shelton, who is currently starring alongside Clarkson on The Voice season 14, Clarkson's own home isn't too shabby.

"[She] has the biggest house I've ever been in in my life. Kelly's house proves that there were more winnings from 'American Idol' than there are from 'The Voice,'" he joked.

While Shelton and Clarkson have been quite competitive with one another on The Voice, they have a close friendship offscreen due to the fact that Clarkson's husband, Brandon Blackstock, is actually Shelton's manager. Clarkson and Blackstock have even been known to double date with Shelton and Stefani.

Although Stefani frequently appears on The Voice, she is not currently starring on the show and hasn't been featured on the singing competition at all since the 12th season.

To see more of Shelton, Clarkson, and their co-stars, including Alicia Keys and Adam Levine, don't miss the new episodes of The Voice Season 14 on Monday and Tuesday nights at 8 p.m. on NBC.
