Caitlyn is the latest celebrity to reveal her secret love in a book.
The transgender athlete, whose transition from male to female has been celebrated in Hollywood films such as “The Lego Movie” and “The Girl with the Dragon Tattoo,” wrote about her “love” for her father and grandfather, according to Vanity Fair.
She described the relationship as “love at first sight.”
The book, “Caitlyn Jenner: My Life on the Run,” is slated for publication in October.
In a book-signing at the White House on Monday, Caitlyn was introduced by President Donald Trump and his wife Melania.
Caitlyn, who won a Golden Globe for best actress in a movie, wrote in the book that she has been “brought up in a very accepting family, in a family where I’ve had many opportunities to explore the world, be who I am, and learn.”
