Jacquelyn Suzanne Gayda-Haas (November 3, 1981) is an American professional wrestler and valet, best known for her work in World Wrestling Entertainment’s RAW and SmackDown! brands and in Total Nonstop Action Wrestling (TNA) as a TNA Knockout. She was awarded a contract with WWE after co-winning the second series of the reality television show Tough Enough.

As soon as Gayda was awarded the Tough Enough II contract, she worked several matches on the RAW and SmackDown! brands. In the second WWE Draft, Gayda and Rico were traded to SmackDown! brand, where they eventually teamed up with Charlie Haas. In September 2004, Haas and Gayda were engaged; their relationship was eventually incorporated into their on-screen characters. Dawn Marie announced the engagement of Gayda and Haas on the September 30, 2004 episode of SmackDown!, implying in the process that she and Haas were “more than just friends.” This led to a catfight between Gayda and Dawn, which in turn led to an intergender tag match at No Mercy pitting Gayda, Haas, and Rico against Dawn and The Dudley Boyz. Gayda’s team won the bout, yet Dawn Marie predicted that the relationship would not last very long. The two divas would catfight once again on December 2, 2004, this time while wearing Christmas outfits. General Manager Theodore Long finally announced a final encounter at Armageddon, appointing Haas as referee. Gayda lost the match, and her fianceé too, as the relationship was broken when Haas revealed he had an affair with Dawn Marie. He then rejected Marie afterwards, saying he did not want either woman.

On the November 26, 2005 edition of iMPACT, Gayda made her debut lashing out at Jeff Jarrett. Jarrett was shocked and frightened by Gayda’s unexpected appearance and soon ordered her backstage. He was heard saying, “It’s not what you think.” After being pushed by Jarrett, Gayda slapped him and then went after his valet, Gail Kim. The following week, Gayda came out again to confront Jarrett. After pushing and slapping, the two had to be pulled apart by officials. At Turning Point, the same thing happened in the main event match. However, Jackie was restrained by officials. On the December 31 show, Don West tracked down Jackie for an interview. She said her being there had nothing to do with a love affair, but rather that Jarrett had promised her a spot on the TNA Roster, but while she was stuck at home, she turned on the television to see Gail Kim in her place. She said she had a big secret about Jarrett that TNA Management would love to hear, but didn’t reveal what it was.

Jackie won TNA’s Knockout of the Year 2005 on the January 14, 2006 edition of iMPACT. At Final Resolution, she ran into Raven after he lost his match. She told him that they had something in common, they were both being screwed by TNA Management. She feuded with Gail Kim in mid-2006. At Sacrifice Jackie announced that she was pregnant, so Kim (kayfabe) fired her. She has not appeared with TNA since and her photos have been removed from the Knockouts portion of the website.
