Spear was crowned Miss Venezuela in 2004, was 5th runner-up in the Miss Universe pageant the following year and had acted in numerous soap operas, most recently in "Pasion Prohibida" for the U.S.-based Telemundo network.
She split her time between Caracas and south Florida, said Dominguez, while Berry lived in Caracas.
Berry's public-facing Facebook page features a series of photos of the couple in blissful days, including a trip to Venezuela's spectacular Angel Falls that preceded their daughter's birth.
Another view into their life was available through the Twitter account of Spear, who had more than 355,000 followers.
Her feed over the last week included brief videos sent on the popular Instagram service.
In one, posted Sunday and described as being taken on the plains, Spear looks at the camera while riding a horse, turns away and then looks back, blowing a kiss.
