Ideally, fans want to see more of Belly's life back home. So, could we see her and the cast return for another round of the Prime Video series? Hollywood Life has all the details below on the future of The Summer I Turned Pretty. Will There Be a Season 4 of The Summer I Turned Pretty? No, there is no season 4 of TSITP. Season 3 was its last.
