Krista J. Allen was born in Ventura, California, but was raised in Houston Texas, by her parents Dalton Earl Allen Sr. and Katherine Mary Allen (née Raposa), who later divorced. Her first encounter behind a professional camera was modeling as a teenager. It didn't take a 35mm camera to realize how much of a beauty the young Krista Allen was. After high school she went to Austin to attend college. Krista was one step away from pursuing a teaching career when she decided to come back to California to accomplish her dream of becoming an actress. She landed a role on the popular TV soap The Bold and the Beautiful as "Shelly". From there she appeared in films and on TV.
In 1996 she dazzled the producers of another popular daytime show, Days of Our Lives. During her time on Days of Our Lives she met Justin Morrit, and they began to date, eventually marrying. In 1997 the pair welcomed a baby boy, Jacob Nolan Morit. Justin and Krista eventually divorced in 1999.
In 2005 Krista started her own T-shirt company named SexBrand with help from her long time friend Katrina McCaffery. In 2006 she changed the name of the company to SuperExcellent. In 2007 they decided to call it quits.
In 2010 Krista and Katrina started a business called Veggie Boom Boom, which started out as just a vegan blog but grew into more. In that same year she became a licensed yoga instructor.
