She had been warned that there was something going on between her fiancé and his new step-mother, and now, Brooke is being confronted with the ugly truth on the Monday, March 27 episode of “The Bold and the Beautiful.”

While walking on the beach trying to find Ridge (Thorsten Kaye), Brooke (Katherine Kelly Lang) saw him and Quinn (Rena Sofer) together, appearing to share an intimate moment. To her horror, she then witnessed them sharing a tender kiss before Ridge walked away. Now, in a preview clip for the latest episode of the CBS soap, Brooke is ready to confront the other woman in her fiancé’s life.

“You’re like a disease that’s come over us one by one, but that is it,” she says in the clip. “Your time is done.”

Nearly everyone has had issues with Quinn over the years, including Ridge, until his sudden turn-around that Brooke now knows is because of the affair. Everyone objected as much as possible, and even boycotted the wedding when Eric (John McCook) insisted on marrying her. Now that Brooke knows Quinn has actually been unfaithful, she will make sure that she understands that Brooke won’t let Eric naively believe his wife is as devoted to him as he thinks.

“I won’t have a husband tomorrow,” she says in the clip. “And neither will you.”

Now, Quinn will need to think fast if she’s going to be able to stop Brooke from exposing the truth and destroying her marriage.

“The Bold and the Beautiful” airs weekdays at 1:30 p.m. EDT on CBS.
