Katie Logan from The Bold and the Beautiful is 54 now
Katie Logan was introduced to The Bold and the Beautiful as the youngest child in the family of Stephen and Beth Logan, with her older sisters being Brooke and Donna Logan, while her older brother is Storm Logan.
When she was young, Katie developed an attraction towards Rocco Carner and was overjoyed when he asked her out. Unfortunately, for her, Rocco quickly developed an interest in her older sister, Donna, causing Katie to become crestfallen when she caught Rocco kissing Donna.
Despite the hurt feelings, Katie eventually gave her blessing for Rocco to marry Donna, and Rocco ended up misplacing his engagement ring by accidentally putting it in Katie's pocket. Katie then proceeded to develop a romance with her college classmate, Kurt Bentley.
Katie would end up fading into the background for a while after her parents were reunited following a lengthy separation that occurred thanks to her father, Stephen, walking out on the family. Her character would come back into prominence in 2007 when she began working for Forrester Creations in public relations.
Later on The Bold and the Beautiful, Katie's older brother, Storm, would shoot Stephanie Forrester and try to frame his own father for the crime. Eventually, the truth came out, and Katie convinced Stephanie not to press charges against her brother.
Storm continued to cause trouble, but by bringing a gun to the house of Ashley Abbott after she rejected him.
Katie followed him, and the two struggled until Katie was accidentally shot by Storm's gun. Deciding that, there was no coming back from this, Storm killed himself in hopes that his heart could replace Katie's and save her life.
Katie's health, though, remained in a precarious condition for a while, as her body didn't immediately accept Storm's heart, causing her niece and doctor, Bridget Forrester, to work on further treatment plans.
Bridget, along with her fiance Nick Marone, further hosted a high-school prom event for Katie as a consolation gift, as she believed that Katie was dying.
Katie developed feelings for Nick and convinced him to sleep with her as a dying wish. That ended up getting Kate pregnant, completely upending Nick's relationship with Bridget, who walked out.
Katie and Nick decided to marry, but the bad blood lingering from their betrayal of Bridget proved too much to handle, causing them to postpone the ceremony.
Nick began getting closer to Bridget again, prompting Katie to flirt with the womanizer Bill Spencer Jr. She ended up grateful that he didn't take advantage of her vulnerable state, and the two began dating for real.
Katie would briefly question Bill's motives when she discovered a DVD of his father exhorting his son to avenge him by taking over Forrester Creations.
However, Bill brought her around to the idea by praising Katie as a survivor and told her that it was a chance to do something important. The two of them proceeded to take over Forrester Creations together, installing Katie as the CEO.
Katie would, however eventually lose the position of CEO after Bill returned the company to the Forrester's control following a blackmail plot from Steffy Forrester.
Recently, on The Bold and The Beautiful, Katie has been involved in the plotline concerning Luna Nozawa's true parentage, thanks to her ties with Bill Spencer Jr. She has been particularly suspicious of Poppy Nozawa's claim that Bill is her daughter's father.
The Bold and the Beautiful airs weekdays on CBS.
