In recent months, the country stars have been the subject of rumors about troubles in their relationship. Now, Shelton is opening up about their marriage – and he tells PEOPLE that there are no secrets between the two.
“[I tell Miranda], ‘I have nothing to hide from you,’ ” he says.
In fact, The Voice judge says one secret to making their marriage work is giving Lambert access to his phone – if she wants it. “That’s always been our policy: ‘Here’s my phone. Go through it,’ ” he says.
“That’s really the kind of trust we have,” Shelton continues. “There are no secrets. [I’ll say,] ‘Go dig through my drawers or my computer if you feel like you need to.’ And that’s been a really good thing, because I don’t want her to ever have any doubts.”
Even amid the rumors, Shelton and Lambert seem undaunted. Days before their May 14 anniversary, Shelton jetted to Bakersfield, Calif., for an unannounced performance at Lambert’s Pistol Annies show. And the two will appear together Wednesday night for the televised benefit Healing in the Heartland on NBC, which will raise money for victims of the tornado in Shelton’s homestate of Oklahoma.
