She offered a halfhearted apology in the interview with the Houston Chronicle.
“I wasn't aware of Denise's reputation and her following,” she said. “I wasn't thinking of how many people watch the show. When you're doing the show and you're in the trenches, you really don't see what everyone's talking about.”
Lisa also reportedly agitated Cosby by marrying musician Lenny Kravitz (another child of Jewish and African-American heritage) and becoming pregnant at age 21. Appearing semi-nude on the cover of Rolling Stone magazine didn't go over well with the Cos either.
She was fired after appearing in only 22 episodes of “A Different World,” then she returned to “Cosby” and she was later fired again at the Cos's urging. She wasn't invited to appear in the show's finale in 1991, and she hasn't participated in any reunion shows since then,
In an interview with Entertainment Weekly in 1998, Lisa said the show “was a big part of my life. My daughter just got all the tapes from my aunt and she'd never really seen my work before. All through her life people had been asking her mom, 'Can I have your autograph?' and she never knew why.”
