Network Ten confirmed the Bachelor finalists would appear in Season Two of the reality show on Twitter.
Both Cass and Brooke were left broken-hearted in this year's series of The Bachelor with Nick Cummins. Cass came fourth in the season while Brooke chose to leave the Bachelor mansion before the finale.
Last season's Bachelor In Paradise starred old Bachelor favourites including Jarrod Woodgate, Keira Maguire, Tara Pavlovic, Michael Turnbull, and this year's Bachelorette, Ali Oetjen.
