Farah Fath and John-Paul Lavoiser met on the set of ABC`s One Life To Live.
As of filming of Dirty Soap in 2011, Fath is dating One Life to Live costar John-Paul Lavoisier, who plays Rex Balsom. In one scene of the show, Fath is seen and heard telling Lavoisier, "If you don't see yourself with me forever, then back out". Fath has commented on the show several times that she wonders when Lavoisier will ask her to marry him. In addition, the show has had both of Fath's parents and Lavoisier's mother on air; Fath's father asks her why she's still with him and Lavoisier's mother dislikes Fath, which provides tension for the show to exploit. In the teases for the season finale, scheduled to be aired on 13 November 2011, Fath tells Lavoisier, "we're through" but, later in the episode Lavoisier and Fath make up and continue the relationship.
In the February 11, 2013, Soap Opera Digest it is stated that Fath and Lavoisier have quietly split, but remain friends.
