Tania was born in Iran to Russian parents. When she was 12 years old, her family came to America where Lemani began her career with a classical ballet dance troupe, but when she traveled to Las Vegas in search of more work, she was offered a job as a belly dancer, not a ballet dancer. She ultimately got her own show in Vegas, as well as offers to dance on television and film. She also began receiving more serious acting roles after a member of her show's audience offered her a role in the pilot for Alexander the Great, starring William Shatner in the title role (although the pilot failed to be picked up as a series). Regardless, Lemani retired from acting in 1969.
