Answer by taking a quote from the following article:

Raised in Tuscaloosa, Alabama, Marshall became a track-runner, cheerleader, and Homecoming Queen in high school before attending the Lee Strasberg Theatre Institute in New York City. She then became a flight attendant. Before her involvement in wrestling, she competed and won the title of 1987 Mrs. Illinois America in Elgin, Illinois and went on to compete in the Mrs. America pageant that same year in Las Vegas, Nevada. She later competed and won in the 1992 Mrs. Texas USA pageant held in Houston, Texas and went on to compete in the National Mrs. USA pageant.

In 1998, Marshall rejoined Jarrett in the WWF. At the beginning of her WWF career, known simply as Debra, she played the part of a shrewd businesswoman, wearing business suits. She also played the part of Jarrett's girlfriend. In late 1998, Jarrett began a feud with Goldust that culminated in December at Rock Bottom: In Your House in a "Striptease match". During the match, Debra hit Goldust over the head with Jarrett's trademark guitar, enabling Jarrett to win. WWF Commissioner Shawn Michaels, however, disqualified Jarrett, and Debra had to strip due to the match's stipulations. As she stripped, The Blue Blazer and Jarrett covered her up. Debra, however, began utilizing a new strategy during matches, distracting Jarrett's opponents by unbuttoning her blouse. She would willingly take off her blouse to show the crowd her "puppies", a nickname originally bestowed upon her chest by wrestler Road Dogg and later utilized by commentator Jerry Lawler. The strategy helped Jarrett and partner Hart defeat The Big Boss Man and Ken Shamrock to become World Tag Team Champions in January 1999. In February, Debra feuded with female professional wrestler Ivory, and Jarrett and Hart retained the tag title in a tag match against Ivory's associates Mark Henry and D'Lo Brown at St. Valentine's Day Massacre. In March, the team lost their tag title to the team of Kane and X-Pac. As Debra continued to manage Jarrett and Hart, a potential storyline developed where Hart and Debra would have an affair, but the creative team vetoed the idea before it played out on-screen. A team name was also in the works--Debra favoring "Talent and Attitude" (T&A)--but Hart died in May 1999 at Over the Edge. Later in the event, Debra and Jarrett lost a mixed tag team match against Nicole Bass and Val Venis. Debra and Jarrett were interviewed moments after Hart's fall from the rafters at Kemper Arena, where Debra was noticeably shaken and fighting back tears of concern for her friend, and was unable to stay in her persona. On May 10, 1999, Debra won the Women's Championship from Sable in an Evening Gown match. Usually, in an Evening Gown match, the woman who forcibly removes her opponent's dress wins. Because Sable removed Debra's dress, she therefore should have been the winner. Commissioner Shawn Michaels, however, ruled that he considered the woman who had lost her dress the winner, crowning Debra the new Women's Champion. Debra lost the Women's Title to Ivory on June 14, due to interference from Nicole Bass. At SummerSlam in 1999 Jarrett faced D'Lo Brown. During the match, Debra and Brown's former tag-team partner Mark Henry interfered on Jarrett's behalf, allowing him to win both the European Championship and the Intercontinental Championship. The following night, Jarrett awarded Henry the European title and gave Debra an assistant, Miss Kitty. At Unforgiven on September 26, Debra turned on Jarrett and hit him over the head with a guitar in the middle of his match against Chyna for the Intercontinental Championship. Chyna pinned Jarrett, but referee Tom Prichard overturned the decision due to Debra's involvement. CANNOTANSWER
