Sheila Marie is an Italian/Irish adult, erotic, horror and comedy actress. Before beginning her adult career she was a glamour, figure, bikini and fitness model. Oxygen channel interviewed her in 2004 while training at a Southern California Gold's Gym for her perspective on fitness, diet and sexuality. She became Fitness Competitor No. 5 in BodyBuilding.com and won a swimsuit competition in a Latin American TV Network.

Sheila Marie phased out of natural bodybuilding in 2004 and began developing a personal floor routine using her own body as resistance. This routine combined dance, calisthenics, yoga and gymnastics. She showcased the results of her new style of training in Michael Stycket's 'Cover Models', in which she showed-off her 22-inch waist as opposed to the 25-inch waist that was typical from her bodybuilding training.

In 2014, she developed a thyroid problem that caused excessive weight gain and was portrayed in the period of 2014 to 2016 as a heavy set model, jumping to a size 9 in jeans from her previous size 3. As of January 2017, she is a 32" x 32" in Levi's 501 jeans as opposed to her previous size of 24" x 32" in the same brand and style.

She is now consuming both meat and dairy products and is recovering slowly. Fans have seen her in numerous films and TV shows in the weight range of 115 lbs to 137 lbs (15% to 25% body-fat) at 5'5"5 and she is currently in January 2017 148 lbs and 33% body-fat.
