A sisterly showdown is scheduled to begin on The Bold and the Beautiful, as Katie (Heather Tom) will finally admit the truth to Brooke (Katherine Kelly Lang) about her feelings for Ridge (Thorsten Kaye).

Katie and Ridge Begin A Relationship!

Brooke eagerly returned from Paris early so she and Ridge could continue going through with their wedding plans, which were halted when Katie fainted at their wedding. While she was in Paris with Hope (Kim Matula), Katie and Ridge decided to act on the feelings they have for one another, regardless of what people will think of them.

Now, in a preview clip for the Thursday, March 6 episode, Katie will tell Brooke the truth.

Katie Faints As Brooke and Ridge's Wedding

"What you think happened...didn't happen," she said. "I'm in love with Ridge."

Besides being in love with Ridge herself, Brooke is also not likely to take the news well because it means Katie has repeated the past, when Brooke stole her husband, Bill (Don Diamont). Despite ending things with him months ago, the sisters have only begun to get their relationship with one another back. However, Katie's news will likely rip their family apart once more.

Meanwhile, Hope will confront Ridge about the whole mess, and will ask him how he could judge Brooke for her indiscretion with Bill when he is doing the exact same thing to her that Bill did to Katie.

"How can you say that what you've done isn't any different from what he's done?" she asked.

Bold and the Beautiful airs Monday-Friday at 1:30 p.m. on CBS.
