Definitely Rose, from Titanic.
She knew the entire time that she had the necklace. Let that guy spend 100s of thousands of dollars trying to find it. Let them pay to fly her out to the ship so she could see her stupid drawing. Then dies on the boat.
Oh, and after the ship sinks, she moves on, has a husband, kids, whole family, yet when she dies and goes to heaven, rather than meeting her husband, she meets the random guy she fucked on a boat one time.
