For Gwen Stefani, dating well is the best revenge, and she certainly is by jumping into a new romance with fellow Voice coach Blake Shelton after her devastating split from husband of 13 years, Gavin Rossdale. As Us Weekly first revealed, the No Doubt songstress, 46, allegedly discovered in February that the Bush frontman, 50, was having a multiyear affair with their sons’ nanny Mindy Mann.

The rugged, 6-foot-5 Oklahoma-born country king, 39, had been coping with his own sudden divorce from wife of four years, Miranda Lambert, after she refused to follow through on their plan to start a family, says a source. Both he and the mom of Kingston, 9, Zuma, 7, and Apollo, 20 months, “have been through horrible marriages and are bonding over that,” a source close to Stefani reveals in the new issue of Us Weekly. “The relationship is very new, but it’s a lot of fun.”

Adding to the thrill? That their coupling might irk their exes. “Blake kind of wants to get back at Miranda,” says a Voice insider.

And Stefani, who directed her team to release a Nov. 4 statement confirming her romance with Shelton just hours before the CMAs, wouldn’t mind delivering a little comeuppance of her own.

“After everything Gavin has done, she hopes he sees what he’s missing,” says a Stefani source of her courtship with the five-time Country Music Association Male Vocalist of the Year winner. “She’s moved on with somebody better who is really good to her. Her being happy is the best revenge. And she deserves it.”
