Blake Shelton, the coach of the Voice has been rumored to intensify his feeling for No Doubt singer Gwen Stefani. Rumors have it that Blake Shelton sealed their fiery relationship with a promise ring.

The No Doubt frontwoman, 46, has been spotted out with what appears to be an engagement ring, but friends say that's not quite true, but both add that the pair has spoken about marriage and it is definitely on the cards for the two singers, reports Xpose.

Moreover, "Blake surprised Gwen with it," an insider told America's Star magazine about the piece of jewellery. "It's more of a promise ring. They want to get married and have been looking at engagement rings, but he just wanted to get her something special sooner to show his feelings. It's a matter of time before she's sporting a big rock on that finger. They're so in love.

Reports surfaced recently that Gwen's ex-husband Gavin Rossdale had called a meeting to discuss 39-year-old Blake's role in his son's lives since the former couple share children Kingston, 10, Zuma seven and two-year-old Apollo, as further noted by the same post. Looking back, both Blake Shelton and Gwen Stefani faced the painful hurdle of divorce. For Gwen, she called time on her marriage owing to the allegations Gavin cheating on her with their family's nanny.

On a different note, Blake is not only happy with his relationship but his current album is gaining momentum as well, reports Rolling Stone.

Even though the rumors were debunked regarding the promise ring, it does not imply that both artists, Blake Shelton and Gwen Stefani are not happy of being together.
