The singer and actress will appear in the season finale of the 10-episode season, which is currently in production. Lovato posted photos from the Austin, Texas, set with both Rodriguez, the series’ creator, director and El Rey Network chairman, and fellow cast member and boyfriend Wilmer Valderrama on Tuesday.
The show travels between Mexico and Texas in the sophomore season, when the disparate cast of characters will come together to face off against an even bigger threat.
The show returns to El Rey Network and Miramax on August 25.
Lovato is represented by CAA’s Charlie Jennings and managed by Phil Mcintyre.
