Later that month, while walking the red carpet at the 2018 SAG Awards, the couple shared their secret to a lasting relationship. &ldquo;Communication,&rdquo; Rockwell told Giuliana Rancic, to which Bibb playfully added, &ldquo;Good sex!&rdquo; Rockwell agreed, emphasizing, &ldquo;Communication and good sex."&nbsp;
