GWEN & BLAKE'S SWEET ESCAPE?

Fans buzz they’re already married!

SINGING sweethearts Gwen Stefani and Blake Shelton seemed to let slip they’d tied the knot after she flashed a diamond-studded band on “that” finger!

Rumors flew after Gwen, 51, posted a social media photo of herself captioned, “she’s getting married,” and then was snapped sporting the dazzling new bling next to her emerald-cut engagement ring.

The lovebirds had just jetted into L.A. from Blake’s native Oklahoma, but after the photos went viral, they stayed tight-lipped about possible nuptials even with friends and family, according to well-placed sources.

“They’re being very cagey but giving every impression they tied the knot in secret at Blake’s ranch in Oklahoma,” tattled an insider.
