Sherri Shepherd’s not taking her show’s cancellation lying down … and she’s making it crystal clear she ain’t backing down without a fight!

TMZ caught up with Sherri in NYC Tuesday, and she doubled down on her vow to keep the “Sherri” show alive … telling us she’s manifesting a new deal and refusing to let the curtain fall just yet.

Watch the clip — Sherri’s all smiles, leaning on faith over fine print … basically saying contracts may have rules, but God’s got the final say.

She also weighed in on former “The Real” cohost Loni Love’s reaction to the “Sherri” show being cancelled — and let’s just say, there’s plenty of feelings in the mix.
