2. Dina Merrill
While you may be wondering who this is, she is definitely one of the richest actresses in the world with a net worth of $5.1 billion. She has been on television, stage, and screen, but the largest part of her wealth actually came from a variety of businesses that she is involved in. She is the daughter of E.F. Hutton, a stock brokerage company, and has married well a few times, too.
