Singer-actresses Christina Milian and Leona Lewis have joined Sony Crackle’s The Oath for its second season. 

Zulay Henao and Kevin Connolly have also joined.

The Oath explores a world of gangs made up of those sworn to protect and defend and sheds light on corrupt and secret societies that are nearly impossible to join. Only a select few make the cut, but once inside, members will do what they must to protect each other from enemies on the outside and from within their ranks. Season two of the action-packed drama finds the Ravens trying to free themselves from their debt to the cartel. The season will examine themes of family and redemption, giving the characters a chance to reclaim their lives as their own, pushing them to find a new path and attempting to conquer their inner demons – all while trying to protect their own lives in the process.

Milian joins as series regular Christine Parks, a second-generation Raven (her father was one of the gang’s founders) and Kraley’s partner. She grew up admiring her dad and wants to follow in his footsteps. Lewis recurs as Amber Hall, daughter of Pastor Greg, who grew up surrounded by the violence in her neighborhood. Presently, she works as a doctor at the local hospital, doing what she can for those in the community that look up to both her and her father.

Curtis “50 Cent” Jackson, under his G-Unit Film & Television Inc., serves as executive producer, along with Todd Hoffman and Dennis Kim of Storied Media Group, Anne Clements and Joe Halpin who is also the series creator, writer and showrunner. 

Created by Halpin (CBS’ Hawaii Five-O, ABC’s Secrets and Lies), who worked as a Los Angeles County Sheriff’s Department deputy in South Central for 17 years, 12 of which as an undercover officer, the series takes ‎an unforgiving look at the complicated dynamics in these organizations and documents the lives of those willing to risk it all to have it all.

The Oath stars Sean Bean, Ryan Kwanten, Cory Hardrict, Katrina Law, Arlen Escarpeta and J.J. Soria.

Production on season 2 is underway in Puerto Rico.
