She learned that her sister was still harboring secret feelings for her husband despite her promise she wouldn't ever go there again, and now, Katie (Heather Tom) will confront Brooke (Katherine Kelly Lang) about her betrayal on The Bold and the Beautiful.

Katie Devastated By Brooke & Bill's Betrayal

She overheard a partial conversation between Brooke and Bill (Don Diamont) where she heard Brooke confess that Bill was the love of her life. Devastated, Katie ran off and started hyperventilating over the betrayal--and collapsed on the floor because of her heartbreak.

Now, a concerned Brooke is making her sure her sister isn't having another heart attack and begging her to go see a doctor, but Katie will drop the bombshell on her that she knows about Brooke's confession, stunning her sister.

Brooke & Bill Try To Fight Their Feelings

"I found you on the floor. You need to call a doctor," Brooke says in a preview clip for the Wednesday, Jan. 27 episode.

"How could you possibly think that my husband is the love of your life?" Katie counters.

After realizing Katie knows how she's been feeling towards Bill, Brooke will find herself attempting to backpedal and assure Katie that either she misunderstood what she heard, or reassure her that she and Bill have no intentions of betraying her again--but Katie won't believe what Brooke tells her.

"You don't even know when you're lying," Katie says in the clip.

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