Ivy Tennant is a character in the Lost novelization Signs of Life.
Tennant is a nervous and beautiful young art student who, for spare income, poses for art classes and pornographic websites. She models for Jeff Hadley in his painting of a parody of Botticelli's Birth of Venus. Shortly there after she has a fairly mundane fling with the professor. He departs for his new job as Artist-In-Resident at a Scottish University, breaking her heart. Little more is known about her.
