There was a huge fight between two houseguests on the Big Brother live feeds Wednesday night.

Head of Household: GinaMarie Zimmerman

Nominees: Amanda Zuckerman & Spencer Clawson

Other houseguests: Andy Herren, Elissa Slater, Judd Daugherty and McCrae Olson

Amanda and GinaMarie had a fight in the dining room, launching several personal attacks towards each other. The fight began when GinaMarie noticed a smirk on Amanda's face as GinaMarie was explaining sleeping arrangements. This led to Amanda calling GinaMarie for her bad attitude over the past few days.

Things escalated when GinaMarie's alleged bulimia was brought up. Amanda called GinaMarie psychotic because of her obsession with Nick while GinaMarie called Amanda a whore for getting into bed with McCrae when he won HOH the first week.

Their fight escalated even more when Amanda got close to GinaMarie's face and tried to intimidate her. Judd came along and broke up the fight between them while everyone else sat and watched.

There was another spat between houseguests on Wednesday night as well, though it was much less extreme. Elissa teased Judd over something that caused Judd to tell her to "shut the f--- up." Elissa was very offended by his comments and went around the house talking about how rude Judd was.

When word got to Judd that Elissa was mad at him, he apologized to her and said he was joking. In an attempt to get her on his side, he said that people wouldn't nominate them together if they knew they were at odds.

As far as Thursday's live eviction, Amanda is still under the assumption that she has the votes to stay. She knows that she has Elissa and McCrae's votes to stay and assumes she has Andy's, too. However, Andy is working with his new Exterminators alliance (him, GinaMarie, Judd, Spencer) and intends on voting out Amanda, his former alliance partner. Andy told Amanda that he was definitely voting to keep her this week.

With Elissa and McCrae voting to evict Spencer and Andy and Judd voting to evict Amanda, there will be a tie on Thursday night's live show. As Head of Household, GinaMarie will have to break the tie and will definitely vote to evict Amanda. She will likely do it with glee after her fight with Amanda Wednesday night.

Thursday night's episode of Big Brother 15 airs at 9 p.m. on CBS and will feature the eviction, a surprise second eviction and another HOH competition.
