If you love The Walking Dead but haven't seen the Season 3 finale yet, you may want to look away now. What we're about to tell you isn't that much a spoiler, but we're covering our bases just in case!

TV Line reports that three cast members will become series regulars when the show returns for its fourth season. Chas Coleman, Sonequa Martin-Green and Emily Kinney will all be bumped up to the main cast.

It's great news for the trio, who play Tyreese, Sasha and Hershel's youngest daughter Beth respectively. Coleman and Martin-Green played the recurring brother-sister duo throughout Season 3, while Kinney joined the show back in Season 2. Oh, and FYI, The Governor will be back for Season 4. He's such a badass, they decided they'd keep him on.

The Walking Dead's Season 3 finale aired in the US on Sunday, and it's due to wrap up in the UK on Fox later this week.
