My Father's Girlfriend (2019)

Weeks after moving to LA, AJ finds herself going home with the aging celebrity musician, Tommy Gunn, only to discover that she has genuine feelings for his unknown, but talented, singer/songwriter son, Adam. Sensing this connection, Tommy sweeps AJ up in a whirlwind romance, giving her a taste of the charms that fame can provide. In an effort to dampen her feelings for Adam, AJ sets him up with her friend, Jessa, who is also drawn to Tommy, and his fame. These women fan the flames of the father-son rivalry. Adam is trying to make it as a musician without his fathers help, while Tommy is jealous of his sons talent and youth. These conflicts come to a head when Tommys ex, Sara, tempts him back into old habits. AJ is left to choose between staying with a troubled rock legend or taking a chance with her boyfriends son.
