Christina Milian is taking The Oath…

The 36-year-old Cuban-American singer, songwriter and actresshas been cast as a series regular on the sophomore season of The Oath, Sony Crackle’s gritty drama from executive producer Curtis “50 Cent” Jackson.

Zulay Henao will recur during Season 2, which has begun production in San Juan, Puerto Rico.

Created by Joe Halpin, The Oathexplores 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 own ranks.

Season 2, which was ordered in April, 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 will play Christine Parks, a second-generation Raven — her father was one of the gang’s founders — and partner of Kraley (Andrew Howard). She grew up admiring her dad and wants to follow in his footsteps.

Milian’s previous credits include Grandfathered and East Los High.

Henao will recur as Carmen Velasquez, the older sister of Ricardo and daughter of Ignacio who, after living most of her life surrounded by violence, is trying to move the family toward a legitimate business.

Henao was a regular on OWN’s Tyler Perrydrama If Loving You Is Wrong.

Cast members also returning for Season 2 include Howard, Law, Ryan Kwanten— who’s also a producer — Cory Hardict, J.J. Soria, Elisabeth Röhm, Michael Malarkey, Isaac Keys, Kim Delaney, LaToya Tonodeo and Braulio Castillo.
