The Scandalous Affairs That Led to ‘The Bold and the Beautiful’s’ Big Brooke-Katie Blowup

The Bold and the Beautiful’s Brooke (Katherine Kelly Lang) and Katie (Heather Tom) went to war once again in an epic showdown in Eric’s (John McCook) office. Years of dirty laundry came into play, even if it wasn’t all spoken. But when Katie mentioned one of the biggest scandals in the CBS soap’s history, Brooke’s hand went flying right across Katie’s face.

Things may never be the same between these two sisters again, but they have weathered other storms. What “dirty little mistake” was Katie talking about and why is there always an underlying tension between Brooke and her little sister?

Brooke’s Most Controversial Move Stunned All

Before there was Hope (Annika Noelle), there was Bridget and that’s how Hope came to be. Brooke couldn’t resist her attraction to Bridget’s young husband and had a scandalous affair with Deacon Sharpe (Sean Kanan) behind Bridget’s back. When Brooke became pregnant, it nearly ruined Brooke’s relationship with her older daughter for good.

Through the years, Hope has even felt like Brooke’s mistake, but nobody dares say it out loud. When Katie said it, Brooke snapped and made a move she might come to regret. Brooke and Katie’s relationship has been on shaky ground for years due to another one of Brooke’s scandalous moves.

Brooke Can’t Stay Away From Katie’s Husband

After giving birth to Will, Katie suffered from severe postpartum depression and actually pushed Bill (Don Diamont) and Brooke to be together. They tried to resist their feelings, especially when Katie realized she wanted to save her marriage. However, Bill and Brooke couldn’t stay away from one another, leading to multiple trysts through the years. After a pregnancy, miscarriage, marriage and divorce, Bill and Brooke decided they weren’t meant to be.
