He has been plagued by rumours that he is cheating on his EX-wife Miranda Lambert.
But Blake Shelton insists he has 'nothing to hide' from the country singer.
The 36-year-old said 'there are no secrets' in his relationship and that he allows his wife to go through his 'phone, computer and drawers' in the latest issue of .
'We have no secrets': Blake Shelton, pictured with wife Miranda Lambert in March in LA, said they have a policy of total honesty with one another in the latest issue of People
He's ready: Blake, pictured in December in LA, said he and Miranda are wanting to start a family soon, and that two years of marriage has prepared him for the next chapter
Recent reports claimed that Blake had a month-long affair with pop country star Cady Grove after the pair flirted over Twitter.
But The Voice judge said he keeps nothing from his wife, and that their number one rule is total honesty.
'[I tell Miranda]..."Here's my phone. Go through it,"' said The Voice judge. 'That's really the kind of trust we have.
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.'
Blake also admitted that he would be jealous if he saw another man chatting up his blonde wife.
'I guarantee you, if I saw some guy flirting with my wife, it would p--- me off,' said Blake, who is wrapping season four of The Voice and getting ready for his Based On A True Story summer tour.
'Of course, I haven't seen a man brave enough to do that - mostly because I think they'd be afraid of her reaction.

The couple, who have been married two years, try not to allow a couple of weeks to go by without seeing each other, but Blake said it isn't always easy to manage.
Miranda, who has said before that 'divorce is not an option', has been flying out to Los Angeles to visit Blake while he shoots The Voice.
'She's been a lot better about finding me if I'm stuck in L.A. She'll always fly instead of going home, even if it's just a day or two,' he said.
'I can't express how important that's been to our relationship and why we're doing so good, because I'm the kind of guy who doesn't want to drive down a hill to go grocery shopping, much less fly across the country.

But Blake has made romantic gestures of his own, including surprising her days before their May 14 anniversary at one of her shows.
But not all his surprises go over too well. When he moved to L.A. he found a mansion, thinking small-town girl Miranda would be swept off her feet by the grandness of it. She wasn't.
'[I found[ this big-ass nice house with a pool,' he said.
'And the first time she ever came, she was like, "This is dumb. Why did you get a house this big?" And I was like, "I thought you'd like it!"'

The singer also admitted that the couple want to start trying for a baby soon.
'I'm thinking about a family,' he said. His marriage has prepared him to take the next step, he said.
'Learning to not be selfish is what has changed in me the most since being married.
I'm thinking on behalf of someone [else] now. Just like I hope she is doing with me.'
