Grant stars in an upcoming Lifetime movie, and the dramatic new flick now has an official air date.

GUYS! Hey, guys. Guys,” an excited Grant tweeted on August 30, “Look for A Mother's Nightmare on the Lifetime network on Saturday September 29. Real life.

Co-starring 90210’s Jessica Lowndes (Adrianna) and Pretty Little Liars’ Annabeth Gish (Dr. Sullivan), A Mother’s Nightmare tells the story of a sweet young high school kid named Chris, who, still dealing with the pain of a recent breakup, starts getting close to a sassy new girl at school. Unfortunately, Chris’s love story quickly becomes a nightmare when his new GF goes sort of psycho and accuses him of assault.
