Kelly Clarkson still can't handle out Gwen Stefani and Blake Shelton, 'Why is she with him?'

The two iconic singers are involved in a friendly quip, keeping the fans fairly entertained so far in the singing reality show.

Kelly Clarkson took a playful jibe at The Voice co-judge Blake Shelton by stating that she was wondering how he and Gwen Stafani were still dating.

According to Inquisitr, Clarkson opened up in an interview about the time she was invited to Stefani's home and was left quite impressed. She stated that she felt her house was "insane."

“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,'” the source quoted the former American Idol winner as revealing.

She could not stop talking to her husband, Brandon Blackstock, who is also Shelton's manager, about Stefani's house for a long time. Clarkson revealed that after being impressed with Stefani's interior decoration, she had to ask herself why was she still with Shelton.

Shelton took Clarkson's playful banter in the positive light as he smiled during the interview and admitted that he was "wondering the same thing." Shelton and Stefani have now been together for a little more two years, the source informed.

Shelton then added his own banter by taking a hit at Clarkson's own home. The country icon said that he was actually surprised that he was invited into Clarkson's home because she owned 'the biggest house' he had ever visited, Inquisitr reported.

Clarkson and Shelton have been throwing playful banter at each other since the beginning of Season 14 of The Voice, which has been one of the biggest highlights of the show so far.

Shelton earlier also reported that, as a new coach, Clarkson had not been going easy on him as well as fellow coaches Adam Levine and Alicia Keys.
