GWEN'S RING OF TRUTH!

"Forgets' wedding band to send Blake a warning

- 

NEW bride Gwen Stefani sent a clear message to hubby Blake Shelton to shape up or ship out when she "forgot" to wear her wedding ring on a late-night TV appearance, sources dish.

The 52-year-old "Hollaback Girl" singer made a big deal about the missing ring, which Gwen coyly insists she forgot to grab out of a cleaning machine.

"I'm so sorry, Blakey," Gwen gushed on the show.

"I love my husband!"

But a friend tells The National ENQUIRER Gwen was giving Blake, 45, a pointed hint of how things could turn out, especially if he keeps piling on pounds and goes on tour with his ex.
