Has Demi Moore found a new guy – or is she just intensifying her workout?

The actress, 49, was spotted Saturday in L.A. with Blake Corl-Baietti, a 26-year-old California personal trainer who also models.

In a 2009 profile on the modeling web site One Model Place, Corl-Baietti says, "As far as my interests are concerned, I am as renaissance as it gets. I love anything outdoors, learning as much as I can, and [gaining] any kind of life experience possible."

Describing himself as "fun-loving" and "honest," Corl-Baietti also says that he "PROUDLY [serves] in the California National Guard and am in college pursuing a degree in kinesiology."

However, the pair aren't dating, a source tells PEOPLE.

Moore, who recently told Harper's Bazaar that she worries that she's "not worthy of being loved," has maintained a low profile since splitting from husband Ashton Kutcher, 33, in November.
