After leaving MNM, she became John "Bradshaw" Layfield's "image consultant", and managed him to the WWE United States Championship at WrestleMania 22.

Hall made her WWE debut on the July 28, 2005, episode of SmackDown! with a gimmick of a "fixer" for the villainous factionMNM (Joey Mercury, Johnny Nitro, and Melina). She also had a "growth" on the left side of her face, which she referred to as a "blemish", the nature of which the announcers constantly speculated over. The gimmick carried over to OVW, where the Blonde Bombers forced her to choose between them and MNM. She eventually chose MNM, but did not stay with that group for very long. As MNM's fixer, she, in storyline, helped them to obtain a photo shoot for the cover of SmackDown! magazine, and helped to fix a problem that Melina had with Torrie Wilson, by helping Melina defeat her.
In January 2007, Hall began a scripted rivalry with Massaro centered on Hall's jealousy of Massaro's recent Playboy appearance; the rivalry turned Hall into a villain and matches between the two mainly resulted in losses for Hall. During the feud, Hall attempted to prove that she was talented in areas beyond wrestling and being eye candy by creating a new in-ring persona, in which she sang badly at every opportunity, but thought she was a very good singer. She later attempted to impress music producer Timbaland by performing a song she claimed to have composed herself, looking for a spot in a video he was preparing and a possible future collaboration on a music project, but he turned her down. Massaro, with whom she had been involved in a rivalry, was one of the wrestlers who was chosen to work with Timbaland instead. Jealous of Massaro's recent successes, she attacked her and, in storyline, seriously injured her, with the reasoning that if she could not appear in Timbaland's music project, neither could Massaro. Following this incident, she had a short rivalry with Michelle McCool, who had come to Massaro's aid, and was annoyed by Hall's singing. She defeated McCool in a singles match on the April 27 episode of SmackDown!, and sang before and after their match. They continued to compete against each other throughout May and June, with McCool coming out on top.
Hall was drafted from SmackDown! to the Raw brand on June 17, 2007, as part of the 2007 Supplemental Draft. The following night, Hall won her Raw debut where she teamed with Melina to defeat Mickie James and Candice Michelle in a tag team match. From then on, Hall mainly competed in tag team matches, wrestling James, Michelle, and Maria. She resumed her singing gimmick not long after, frequently appearing in backstage and in-ring segments, including a stint as one of the contestants for the WWE Idol segment on the August 13 episode. She also entered into an on-and-off angle with ring announcer Lilian Garcia stemming from her jealousy of Garcia's flourishing singing career. In October, Hall formed an alliance with Melina, and the pair teamed together on numerous occasions throughout the end of the year. She also competed in the 10-wrestler tag team match at Survivor Series, but her team was not successful.
