Brooke Logan was part of a storyline in which a character named Ridge chose to marry Taylor, and on the wedding day of Ridge and Taylor, Brooke ran to find them, thinking she was pregnant with Ridge's child, which a paternity test falsely showed that he was.
In the end however, Ridge chose Taylor as he did not want to be the cause of the end of Brooke and his father's marriage, and hoped if he chose Taylor, Brooke would stay with Eric. On the wedding day of Ridge and Taylor, Brooke ran to find them thinking she was pregnant with her and Ridge's child, when in fact she was pregnant with her and Eric's second child, Bridget. A paternity test was later conducted, with Sheila Carter tampering with the results and having everyone believe Ridge was the father; it would be years later before the truth about Bridget's true parentage was revealed.
