"The Voice" has released it's first promotional video for it's upcoming seventh season which features returning judges Adam Levine, 35, and Blake Shelton, 37, as well as newcomers Gwen Stefani, 44, and Pharrell Williams, 41.

The hit series will return for its seventh season on September 22 and the two new judges will take their place in the spinning red chairs that have since been vacated by previous stand-in judges Usher, 35, and Shakira, 37.

In the new promo, the judges are seen smiling and having fun together while in the background, the 2005 song "Hollaback Girl," co-written by Gwen Stefani and Pharrell, provides an upbeat vibe.

According to E! Online, the blind auditions are currently underway and are being filmed for the upcoming season. The judges, of course, would not leave their fans hanging and decided to throw the Twitter-verse and Instagram audiences a bone by posting some behind the scenes pictures of the fun on Friday!

Newbie Gwen posted a candid photo of herself with Pharrel in the background and tagged it with the caption: "sneak peek. @Pharrell #TheVoice."

At the same time, coach Blake also posted this little number of himself with a solid cowboy hat and a smiling Pharrell. He injected a little humor and said, "You know what they say about big hats...right @Pharrell? #TheVoice #Season7."

The appearance of Stefani and Williams was officially announced on May 5 during "The Voice" season 6's live rounds.

Recently, Maroon 5 frontman and coach Adam Levine aired his sentiments about "The Voice" and opened up to The RollingStone about the show's areas of improvement despite its many successes.

"I'm not going to lie to you, I think there are problems," he said. It's important for the show to find a singer that the public can relate to. It has not had any major stars that have been able to launch successful careers like those who have been featured on other shows like Carrie Underwood or Jennifer Hudson.

"Millions... watch the show every week and fall in love with a singer, then you don't hear much from them. We haven't had a breakout success like Kelly Clarkson or Carrie Underwood," Levine shared. "[The show is] very successful, but it's got a ways to go."

If you can't wait for the new season to start, the good news is that "The Voice" tour is just about to kick off and it begins tomorrow in San Antonio. More about this on the show's website.
