Leah Remini, Sharon Osbourne Leah Remini, Sharon Osbourne

Seven months after getting fired from The Talk, Leah Remini is finally ready to talk. Remini, 41, opened up Monday about why she and fellow co-host Holly Robinson Peete were let go after just one season — pointing the finger at co-host Sharon Osbourne.

"Sharon thought me and Holly were 'ghetto'. . . we were not funny, awkward and didn't know ourselves," Remini wrote on Twitter. "She has the power that was given to her."

Leah Remini confirms Talk exit

Remini began tweeting in reaction to an interview Osbourne, 59, gave on The Howard Stern Show. Osbourne rebuffed Remini's accusations Tuesday, also on Twitter. "In response to Leah Remini's continuous comments that I had her fired from The Talk, let me just go on the record to say I had absolutely nothing to do with her departure from the show and have no idea why she continues to take to Twitter to spread this false gossip."

"Leah knows that I have never been in the position to hire or fire anyone on the show," she continued. "That being said, my only wish is that Leah would just stop all this negative, unprofessional and childish behavior. It's been seven months. It's time to move on. Leah is a very talented actress and I only wish her happiness and success."

CBS renews The Talk for third season

Remini and Robinson Peete's exits followed that of Marissa Jaret Winokur, who left the show in January of 2011. After several guest co-hosts, Remini and Robinson Peete were permanently replaced by Aisha Tyler and Sheryl Underwood. Sara Gilbert and Julie Chen also appear on the daytime chat fest, which was recently renewed for a third season by CBS.

Despite Osbourne's comments Tuesday, Remini doesn't seem to be backing down anytime soon. "If someone wants me to stop, they should call a lawyer and tell them what I am NOT telling the truth about," she said. "We can go from there."

Next up for Remini? A role in the ABC comedy pilot White Man Van.
