Blake Shelton and Adam Levine have been taking jabs at one another on “The Voice” since Season 1 premiered in 2011. Co-stars have come and gone — we’re looking at you, Christina Aguilera, Gwen Stefani, Ceelo Green, and Pharrell — but it seems these two are here to stay.

NBC Chairman Robert Greenblatt opened up about casting for the show during the summer Television Critics Association press tour. As was reported by Entertainment Tonight, he told reporters both Shelton and Levine are keen on being a part of the show for a multitude of reasons, including “the paycheck.” He added that “The Voice” cast can be compared to that of any scripted series — some characters will fade out, but some will be there through the series’ end.

“If I can compare it to a scripted show, you kind of have your series regulars that you love. They are always hugely popular whenever we do testing and we’ve done a fair amount of that over 11 cycles,” Greenblatt explained. “We think they’re the pillars of the show and then we have this revolving family of Gwen [Stefani], Pharrell, now Miley [Cyrus] and Alicia [Keys] joining the pack.”

Cyrus and Keys were confirmed to be joining the cast just one day after Season 10 ended. NBC released a statement in which they officially announced the casting shake up, with the two female musicians stepping in to replace Pharrell and Aguilera. The network’s president Paul Telegdy said that Cyrus and Keys would bring with them plenty of “expertise and energy.” He added that they were looking forward to having them on the show, but shared no more about what fans should expect in Season 11.

“The musical expertise and energy these two incredibly talented women will bring to the show is remarkable,” Telegdy said (via Variety). “We’re thrilled that they’ll be joining Adam and Blake in what we know will be a magical 11th season.”

Season 10 wrapped on May 24 with competitor Alisan Porter being crowned the winner. The Massachusetts native was a part of Aguilera’s team and gave her her first “The Voice” win in her final season with the competition series. Porter told International Business Times at the time that she was happy to bring home the title for her coach, noting that “she’s been at it since day one and she’s had some incredible talent.” The mother of two was said to be preparing to get into the studio to lay down tracks for her first album after “The Voice.” While she had not lined up any collaborations with her co-stars, she said she was open to the idea. Porter also had dreams of working with Sia, who performed during the Season 10 finale of “The Voice.”

“I would love to write with any of them and sing with any of them at any time,” she said. “We’re such a family and I think they’re all insanely talented.”

It remains unclear when Season 11 will premiere on NBC. The show is slated to return in the fall.
