World Championship Wrestling

In 1999, Stacy entered a contest held by WCW to find a new member of their Nitro Girls dance troupe, which she won. Initially a Nitro Girl, Stacy would perform dance routines every week on WCW's flagship show Monday Nitro under the name Skye. However, this didn't last long as she soon accepted a larger role and became a valet using the provocative stage name Miss Hancock (originally Miss Handcock), briefly serving as an associate for the tag team of Lenny Lane and Lodi dubbed "Standards and Practices". Despite wearing business suits, her character would often climb on top of the announcers table and start dancing sensually, much to the announcers' and fans' delight. It was also during this period that she began using what would become her trademark ring entrance.

Hancock was next brought into a brief feud with Kimberly Page, but Page quit the company in the beginning of the feud after problems with Scott Steiner and a refusal to wrestle Keibler on Pay-Per View.She began a feud with the Misfits in Action stable, which saw her fall to Major Gunns in a mud wrestling match at New Blood Rising.

In another notable angle, Stacy feigned pregnancy and later broke up with Flair. Originally, the angle called for her to reveal the baby's father as Vince Russo. She began to use her real name and became the valet for Shawn Stasiak.

2001-2003

When WCW was purchased by the WWF in 2001, her contract was one of 24 that were retained by the WWF. She portrayed a heel character in The Alliance. She made her WWF TV debut on the June 14, 2001 episode of SmackDown! when Shane McMahon brought her to the ring to distract Rhyno, causing him to lose a match.

Stacy was originally drafted to the SmackDown! brand in 2002, where she participated in a comedy segment involving WWE Chairman Vince McMahon hiring a personal assistant. McMahon was ready to hire another attractive female until Stacy interrupted and demonstrated why she should get the job by giving him a table dance. Stacy became Vince's assistant as well as his on-screen mistress, frequently shown flirting and making out with him in backstage segments, until Stephanie McMahon became general manager of the SmackDown! brand. Dawn Marie made her debut on SmackDown! as Vince's legal assistant, who competed with Stacy for McMahon's affections. The angle confused many who were curios as to why to attractive young women would be fighting over a mean-spirited old man, rather than a young wrestler.

A match was set for WWE Unforgiven, the stipulation being if Test won, he would not only retain Stacy's services, but those of Scott Steiner as well. During the match, Stacy attempted to distract Test by lifting her skirt and wiggling her butt for the crowd. This was unsucessful. Stacy then attempted to whack Test with a chair, but he ducked and she accidentally hit Steiner instead. As a result, Test won the match and the services of both Keibler & Steiner. Steiner would then turn heel by attacking Stacy when she botched another interference on the next RAW. For a time, Test & Steiner would work as a tag team, sharing the services of a miserable Stacy. Finally, General Manager Mick Foley put a stop to the abusive Test and Steiner and freed Stacy from her obligatory contracts with the pair by temporarily firing them.

2004

Stacy was chosen to record a track on the album WWE Originals. She and WWE music producer Jim Johnston recorded the track "Why Can't We Just Dance?" for the album. Other tracks were performed by Superstars such as Chris Jericho, Lilian Garcia and John Cena, each of which had their own music career. Her track was used on an episode of RAW for herself, during the 2004 RAW Diva Search and even on the Viva Las Diva of the WWE DVD.

As one of the more popular RAW face Divas, Stacy took over the 2004 RAW Diva Search for a few weeks. That was followed by a dance competition with Molly. This led to a push with her participating in several tag matches against the heel girls, then WWE Diva, Gail Kim, then heel, Trish Stratus and Molly Holly. Her partners were WWE star, Nidia and then babyface, Victoria. Stacy showed off much improved wrestling skills, managing to get upset wins against Molly, Gail, and Trish. She even got herself a Women's Championship title match on October 11, 2004. However, Trish defeated her to retain the title.

Stacy was voted as the 2004 WWE Babe of the Year, being the first WWE Diva to defeat Trish Stratus in the Babe of the Year competition (Trish was 2001-2003 Babe of the Year). As a result of this, Stacy appeared on RAW following her victory and told everyone that she would bend over backwards to make the fans happy.

2005

Stacy soon began an angle with popular superstar Randy Orton. After kissing him on the cheek during a backstage segment on RAW, there looked to possibly be a romance there. Randy even saved her from receiving a Pedigree from the villainous Triple H.

Stacy and fellow RAW Diva Christy Hemme were moved to SmackDown! as part of a trade, bringing Torrie Wilson and Candice Michelle to RAW. Keibler started a short feud with Jillian Hall, which ended up with the two having a match on Velocity, during which Hall captured the victory through cheating. This would prove to be Stacy's last match with WWE.

2006

Keibler appeared on the hit show Dancing with the Stars (see Outside of wrestling), placing third. Recaps were aired weekly on RAW, which was believed to be because of a conflict with SmackDown! and UPN not wanting to promote a rival network. After a few weeks, her profile was moved from SmackDown! back to RAW.

In April 2006, Vegas Magazine reported that Stacy Keibler was done with WWE and moving on to other endeavors. Keibler posted a message on her official website saying that her WWE contract expired on July 21, 2006, and she went on to sign a contract with Touchstone Television, which is owned by Disney. Stacy's profile has since been removed from the RAW roster and Divas Section on the WWE official website.
