The two appear to have reconciled since Alvina first filed for divorce from the actor back in September 2015, reported E! News.
Stewart had filed for divorce citing the ever-so-popular "irreconcilable differences" as the reason for the split but eventually changed her mind.
The couple, who were high school sweethearts, got married in 1999 and have two children -- Kyra Anderson, 19, and Nathan Anderson, 15 -- together.
Anderson's acting career is on rise with the popularity of the comedy drama "Black-ish".
