Is Blake Shelton Dating Gwen Stefani?

The tabloids are swirling that Blake Shelton and Gwen Stefani have a little something going on.

Is it true? Ah, who knows, it's the tabloids. But, where there's smoke, many times big flames are a burnin'!

Both filed for divorce earlier this year and they're both on the upcoming season of "The Voice". And Life & Style magazine thinks that's too much a coincidence not to exploit.

They allege the two fell for each other when they started doing "The Voice" together.

A source says, "They're trying to keep it on the down-low, but it's not happening partly because they're all over each other . . . everyone on set [knows]."

And apparently Miranda Lambert has found out about the romance and is none too happy about it. Life & Style says she used to consider Gwen a friend but now that's over.

For the record, there has been no denial or confirmation yet from Blake or Gwen on the matter.
