The stars announced their involvement and the titles of the show in a video on The Boys' social channels, while Shelley Conn, Sean Patrick Thomas and Marco Pigossi have also been confirmed to star in the series.
You can watch the announcement video on The Boys' official Twitter account here.
In the video, Sinclair says she is "so excited to be a part of this show" which features "love and beautiful relationships and tons of action and superheroes", while Phillips adds that it will include "lots of hormones, and drama, and mystery".
As fans have come to expect from The Boys, Broadway teases that the new show will be filled with "blood, guts and everything else", while Pardomo adds "It's f***ed up, you're gonna like it".
The official synopsis for the show states that the show is "an irreverent, R-rated series that explores the lives of hormonal, competitive Supes as they put their physical, sexual and moral boundaries to the test, competing for the best contracts in the best cities. It’s part college show, part Hunger Games’— with all the heart, satire, and raunch of The Boys."
