Katie's romantic life did not remain calm for long, as she started dating bad boy Bill Spencer shortly after his failed stint at romancing her sister, Donna. The romance with Katie and Bill was highly unexpected, and highly unlike, due to Spencer's desire to steal Forrester Creations from the Forresters—and Logans. After hooking up with Bill, Katie was appointed the new CEO of Forrester Creations, which was a newly acquired division of Spencer Publications. Bill's motives towards her were unclear to Katie, especially after she saw a DVD that was made by Bill's father, Bill Spencer, Sr., that he had left to his son, asking Bill, Jr., to take down Eric Forrester, Donna and Brooke Logan, after what they had done to the woman he truly loved, Stephanie Forrester. Katie then got Bill's word that he was not using or romancing her to pursue his father's vendetta against the Forresters. They then got married in Katie's old neighborhood, with their nearest and dearest alongside them. Bill's sister Karen, Katie's mother and father Beth and Stephen, were those who were especially there for the ceremony.
