Christina Aguilera's colorful personality has almost overshadowed her incredible talent. The gifted singer is an outgoing Sagittarius who was born December 18, 1980 in New York City. Her look has gone from dark and dirty to white and clean, showing a range of images that continue to surprise the public. Her brilliant voice, though, has been a constant in a career that began when she was just a child. Sagittarians like to have fun, but Christina ups the ante with imaginative Neptune conjunct her Sun in this fire sign. Neptune is the planet of fantasy, so it's natural that she would have almost as much fun playing roles as singing songs. The prominent position of Neptune adds a bottomless well of creativity that Christina may apply one day as an actress. Venus -- the planet of style and beauty -- was also in Sagittarius when Christina was born, adding another layer of flamboyance to her personality. And just to kick it up a notch, she has Uranus -- the planet of unconventionality -- next to her Venus. This is often associated with a desire to shock and surprise, which she has done quite well. It also adds inventiveness to her music and restlessness as an artist. She never wants to do the same thing twice.

There is plenty of substance in her chart as well. Christina may appear wild at times in her act, but she knows exactly what she's doing. In fact, the girl is downright ambitious. She has Mars, the action planet, in "taking care of business" Capricorn. There's a natural tendency to push herself hard. Capricorn wants to climb to the top, so she's probably rather competitive on a professional level as well. Christina's Moon is in another earth sign, Taurus, which may account for her voice. The sign of the Bull is associated with the throat and many famous singers have it strongly placed in their charts. In addition to the sensuality it gives, the Moon in this Venus-ruled sign also has a good sense of the bottom line. Also, Jupiter and Saturn -- the career planets -- were joined on the date of Christina's birth, an alignment often associated with culturally important individuals. This close connection of the planets of expansion and contraction is another indication that she's well aware of her impact and has clear-cut goals for her professional life. The richness of Christina's chart is this mix of pure talent and the common sense to apply it with purpose. She'll be a star as long as she wants to be.
