Jenna Jameson and one of her two boys with Tito Ortiz were rushed to the hospital in an ambulance last night around midnight -- after her son Journey began projectile vomiting and losing consciousness shortly after 11 PM.

TMZ spoke with Jenna, who told us she was by herself when her son became sick -- and tells us she thought the best course of action was to call 911 for an ambulance.

Jenna tells us Journey was "hydrated" at the hospital -- and released a few hours later. Jenna also says that doctors informed her that Journey is most likely suffering from a stomach flu.
