Hemme debuted in Total Nonstop Action Wrestling on April 23, 2006 at Lockdown 2006, giving an envelope to commentator Mike Tenay containing the announcement that Larry Zbyszko had been placed on probation and Raven (whom Zbyszko had fired earlier that year in kayfabe) had been reinstated. In addition to her hosting role on TNA iMPACT!, she is also the co-host of the Internet show TNA Global iMPACT! with Jeremy Borash. At TNA Hardcore War, Hemme refereed a match between Traci and Gail Kim. In July 2006, she was featured on Spike TV's Women of Action special.
In September 2006, Hemme recorded a song entitled "Society Box", which was featured on TNA's November 21, 2006 music release, 3rd Degree Burns. She has also been traveling to Windsor, Ontario to train under TNA agent Scott D'Amore in between TNA TV tapings. She also won TNA's Knockout of the Year for 2006.
On January 14, 2007 at the Final Resolution 2007 PPV, Christy came out and interrupted the Voodoo Kin Mafia and cut a promo about women's involvement in wrestling today. She said that she wanted to wrestle too - and the mostly male crowd in the TNA arena jeered her. Kip James called her a slut, which garnered him a slap from Hemme, while B.G. James attempted to play peacemaker.
In the following weeks, Kip and Hemme would be shown getting into a fair few arguments over his lack of respect for her, and for women as a whole. Hemme made her TNA in-ring debut at Against All Odds 2007 where she wrestled and defeated "The Big Fat Oil Guy" in a Tuxedo Match.
On the March 8 version of iMPACT, Hemme asked Jim Cornette for a match pitting VKM against her a new, previously undisclosed, team, at Destination X 2007. Cornette consented and "booked the match" in storyline. On the pay-per-view, Hemme introduced The Heartbreakers (formerly The Heart Throbs of the WWE). Despite Hemme's attempts to give Kip James a "low blow", VKM defeated her team, who she later browbeat at ringside. Hemme later announced that she had found another team to face the VKM. At Lockdown, the mystery team this time was Serotonin, but VKM defeated them as well.
She recently brought in The Basham Brothers as her new perminent tag team in her battle with VKM.
In November 2006, Hemme participated in the Queens of Chaos shows in Paris, France. She wrestled two matches, losing to former WCW talent April Hunter. She then defeated British wrestler Minx to earn the right to referee the championship match, which was eventually won by Hunter.
Hemme made her acting debut in the film Fallen Angels, portraying the deadly sin "Lust". She will also be appearing in another horror film tenatively titled The Dead Season, playing a zombie
