Gemini (May 22-June 21) are said to have a dual nature. The astrological symbol for Gemini is the Roman numeral for two, representing twins and duality.

Twin sisters Mary-Kate and Ashley Olsen are Geminis. Last year the 21-year-old power duo earned $17 million, and they are planning on releasing a coffee table book about their fashion inspirations.

Gemini can be fickle. Those born under this sign represent the yin and the yang, or the law of opposites. It can be no coincidence that Anne Heche is a Gemini. She famously dated Ellen DeGeneres but later married a man. She divorced and is now dating her "Men In Trees" co-star James Tupper.

Geminis are said to have a dual nature, sometimes acting as two different personalities. Angelina Jolie, once the bad girl of Hollywood who used to wear her ex-husband Billy Bob Thornton's blood around her neck, has transformed into a goodwill ambassador and mother of four - make that almost five. Or is she expecting twins?

Intellect is another Gemini quality. Did you know Natalie Portman graduated from Harvard University with a degree in psychology? She also speaks fluent Hebrew, French and Japanese.

Geminis are very talkative and enjoy lively conversation. Drew Carey certainly fits into this category. His current gigs are hosting "The Price Is Right" and "The Power of 10." He spent nine seasons on "The Drew Carey Show" and eight seasons on "Whose Line Is It Anyway?" (which co-starred another Gemini, Wayne Brady).

Adaptability and versatility are also Gemini characteristics. On screen Johnny Depp has embodied these traits. From a swashbuckling pirate to a murderous barber, he is able to seamlessly change characters.
