Blake Shelton and Gwen Stefani could no longer contain their PDA as the dating co-coaches are already openly flirting on "The Voice."
During last week's live taping, for example, Gwen Stefani and Blake Shelton reportedly ratcheted up the flirting, particularly when the cameras were off and only the live audience was watching.
"Right when they called for the break, Blake ran over to Gwen's chair. They were talking close and laughing until makeup duties called," the witness told People.
People also noted that fellow "The Voice" coaches Adam Levine and Pharrell Williams don't quite know how to react with Gwen Stefani and Blake Shelton flirting.
During the performance of contestant Amy Vachal, for instance, Miranda Lambert's ex praised the acoustic rendition of a Drake song.
"I don't think there's ever been a more elegant and classy performance of a song about a booty call in the history of music," Shelton said. "I mean that was, like, unbelievable. I hear that song on the radio every day. That song's so big even I have heard it."
"You know that song?" Adam Levine asked the country star.
And Blake Shelton responded, "Gwen sang it to me on the Tonight Show one night, so..."
Host Carson Daly immediately deflected the awkwardness by giving the stage to Pharrell for his comments.
The report came on the heels of the article from Us Weekly that claimed Gavin Rossdale had a long affair with the nanny, Mindy Mann, which was the reason for the divorce with Gwen Stefani.
"Back in February, Stefani, 46, uncovered Rossdale's long-term affair with Mann, who cared for the couple's three sons, Kingston, 9, Zuma, 7, and Apollo, 20 months," the report claimed.
"At the time, the No Doubt frontwoman discovered explicit texts between Rossdale and the nanny - including nude photos of Mann and their plans to meet up for sex - on the family's iPad."
Gwen Stefani and Gavin Rossdale announced their divorce earlier this year, following almost 13 years of marriage.
The divorce statement said, "While the two of us have come to the mutual decision that we will no longer be partners in marriage, we remain partners in parenthood and are committed to jointly raising our three sons in a happy and healthy environment."
Gwen Stefani and Blake Shelton went public with their relationship during the CMAs, weeks after denying that they are flirting on the set of "The Voice."
And Miranda Lambert wasn't surprised about Gwen Stefani and Blake Shelton dating.
"They were always pretty flirty. Miranda and Blake were on the rocks on and off and knew that this could always be a possibility," an insider told E! News.
