"Liv and Maddie" launched on the Disney Channel in 2013 and has become a fan favorite. The sitcom, which has run for three seasons and just got renewed for a fourth in December, tells the story of twin sisters, Liv and Maddie Rooney (Dove Cameron) and their wacky family. While cast members prepare to film Season 4 of the show, it sounds like "Liv and Maddie" could be heading towards the final chapter. Actor Joey Bragg revealed to International Business Times that the show isn't officially ending yet, but Season 4 could be the last.

"I thought the show might’ve been done after Season 3, but then it got picked up for fourth," Bragg told IBTimes. "It’s very rare Disney Channel goes for a fifth." 

The 19-year-old actor revealed that not only could the show be nearing the finish line, but that there are going to be some big changes when Season 4 premieres. 

"It’s going to be different than it’s been the past three seasons. I’m not going to give anything more away, but there’s definitely going to be a change in probably the poster, opening credits and family dynamic all together," Bragg dished.

Bragg wouldn't say exactly what would be different, but he said he had just received an email about the change in Season 4. However, he said he trusts everyone involved in the show to adapt. "I think we’ve improved every season we’ve done this show and I don’t think that’s going to change."

Not only does he believe that the show has improved each season, but he also said he feels his job portraying Joey has also gotten better. At first, the actor was challenged by adapting to making humor for a Disney channel show after performing a different kind of comedy in his stand up act. As he went through each season, Bragg was able to figure how to use his humor and improv skills to play more towards kids on the show. 

"In the first couple of seasons, I feel like I was still finding my footing, but now when I get a script for 'Liv and Maddie,' I trust my choices and I feel more confident," he revealed.

Aside from getting more confident in his role, the onscreen relationship between Joey Rooney and his brother Parker (Tenzing Norgay Trainor) has also developed over the three seasons of the sitcom. Bragg said he and Trainor are basically best friends in real life and that Trainor has grown so much physically and mentally since the show started in 2013. 

"First of all he hit puberty, that’s a huge deal for him. He’s going to start discovering a lot of really fun things," Bragg joked. "But also the relationship we have has grown from sort of like a big brother/little brother to friends. When you work in a giant windowless box with somebody for as long as we’ve worked together, you’re forced to be as close as two people can humanly get without getting married."

While Bragg is close with Trainor, he also noted how impressed he is with Cameron, who plays both Liv and Maddie. He said he's "blown" away with how she's able to portray both characters while separating them into two different people.

With "Liv and Maddie" possibly heading into it's final act, Bragg said he's not sure what's next for him, but he knows he wants to start doing more stand up comedy again. He added that being on the Disney Channel show has opened doors for him, as well as taught him a lot about acting.

"'Liv and Maddie' has put me in a great position to where I have met a lot of incredible people and I learned more than you can learn in a film school in these four years and I think I’m ready to create my own thing and see where that takes me," Bragg said.

"Liv and Maddie" Season 3 is currently airing Sundays on the Disney Channel.
