Blake Shelton's Ten Times Crazier Tour is still more than three months away, but the singer has already sold out two of the biggest venues on the trek. Both the Hollywood Bowl in Los Angeles and New York City's Madison Square Garden have already sold out, even though it's his first time to play in either location.

“I’m in LA to film 'The Voice' and I drive by the Hollywood Bowl on my way to the set. It is such an iconic venue in LA and I have wanted to perform there for a long time,” he says. “Then there is Madison Square Garden. Hands down, there is not one artist who doesn’t dream about playing Madison Square Garden -- it's mind blowing to think I’m performing at Madison Square Garden and the Hollywood Bowl, let alone selling them out."

The Oklahoma native says he doesn't deserve the credit for the career milestone.

"I’m incredibly thankful for my fans selling out both these shows so fast," he adds. "I promise the band and I will bring you a show you won’t forget. I love you guys!”

Shelton isn't the first country artist to sell out both venues. Jason Aldean sold out the Hollywood Bowl and Madison Square Garden as part of his 2013 Night Train Tour.

The 37-year-old is currently in California, filming Season 5 of 'The Voice,' but he says he is eager to relaunch his Ten Times Crazier Tour, which began last year.

“I cannot wait to get back out on the road,” he says. “I had so much fun playing songs from ‘Based on a True Story…,’ and getting to see the crowd’s reaction to those songs was unforgettable. It is one of the most validating things for an artist like me, to have people sing along to your songs…it means what I’m doing is right and no matter what I’m doing, whether it is ‘The Voice’ or a TV special, absolutely nothing compares to playing live for me.”

The 'Mine Would Be You' singer is also feeling generous for the upcoming tour. One dollar from each pre-sale ticket will go to his Thunderclap campaign, to raise money for ACM Lifiting Lives, which raises money for several causes, including grants for music education and music programs, and financial assistance.

Shelton will return for the fourth year as host of the 2014 ACM Awards. For the second year in a row, Luke Bryan will serve as the evening's co-host. Shelton is nominated for five ACM awards, including the night's highest honor, Entertainer of the Year.

Shelton's Ten Times Crazier Tour kicks off on June 20 in Austin, Texas. See his complete concert schedule here.
