Cosmopolitan, the "Night School" actress recalled being offered $10 million to endorse a product, but she rejected it because it made her "feel like s***.""I've turned down $10 million just to do a post because it didn't represent my brand," she said. "I turned down $10 million because my soul is worth more than that to me. My spirit, my integrity, how I want to be able to look at myself in the mirror every day."Tiffany, who was once homeless and living in her car, didn't detail what she was asked to endorse, but said she'd "rather be flat broke" than take money for something she doesn't believe in.
