Wendy called "the grand liar" during her following revealing to Melissa that it was Teresa who told her to yank ponytail earlier this season.
She said "It's really kind of disgusting cause [Teresa] gets caught out there."
Wendy went on she doesn't want to see clips of the mother of four in this kind of situation because: "That's the old, crusty Teresa that makes you say 'I don't feel sorry for you at all.'"
A new preview clip for tonight's finale shows tell Teresa about Melisa and Danielle's discussion.
Melissa said in the clip: "She [Danielle] said she was on the fence and said 'I don't know'. And then you [Teresa] said 'Do it.'"
A shocked Teresa replied: "She said that?"
Margaret denied the accusations: "I don't believe it, you would never do that."
Teresa added: "I feel bad, I hope they don't use this."
But Melissa confirmed producers would use the footage during the show.
Teresa then flipped off a cameraman, threw her drink and stormed out of the party.
