"The BBC have been so supportive of this project from the get-go and to be able to get this show in front of American audiences at the same time via HBO Max is truly exciting," Matafeo told Deadline.
"I'm thrilled we get to make it, otherwise it would've technically just been a creepy fan fiction script that I submitted to the national broadcaster. The team we've brought together for this series are absolute dreamboats and I'm super excited to be working with them."
"The minute we were introduced to Rose and Starstruck, we knew we had something special," said Sarah Aubrey, head of original content at HBO Max. "She is exactly the type of original, culture-forward creator we are excited to be working with at HBO Max and we are looking forward to a long partnership."
Shane Allen, BBC's comedy commissioner, described Matafeo as "fully formed and instantly magnetic".
"Her assertive millennial female voice is the perfect fit for BBC Three given the strong track record we have in launching sitcoms that speak to a younger audience. Prepare to be utterly enchanted by her winning blend of whip smart writing and the rich character world she has created."
