SOAP SISTER V. SOAP SISTER!

Remember when The Bold & the Beautiful’s Bill had that awesome idea where he and Brooke would have an affair so that Bill could be a better husband to Brooke’s sister, Katie?

Well, that didn’t work out so well. Now Katie knows, and though Bill tried to pin the blame on Katie’s recent fling with alcoholism, she preferred to hold him and her sister responsible.

B&B’s Katie and Brooke aren’t the first pair of sisters to fight over the same man. (Though is it truly fighting if neither is particularly sure they want him anymore?) Heck, Bill isn’t even the first man Brooke and Katie have in common. There was Ridge. There was Nick. (To be somewhat fair, B&B is a half-hour show with a smaller-than-average cast.)

A sister versus sister love triangle is a soap-opera staple. Read some of our favorites, past and present, at Entertainment Weekly!
