One of Jenna Jameson's twin baby sons was taken to the hospital by ambulance on Monday after losing consciousness at the family's California home.

The former adult star called 911 after one-year-old Journey began vomiting and then passed out at around 11pm local time.

An ambulance raced to the scene and escorted mum and tot to a local medical center, where Journey was "hydrated", reports TMZ.

Doctors told Jameson her son was probably suffering from a bout of stomach flu.

It marks the latest in a series of dramas for the the former porn star and her partner Tito Ortiz.

The wrestler was arrested on domestic violence charges on April 26 after reports of a dispute between him and Jameson. The mixed martial arts star then accused his partner of abusing prescription drugs.

Both parties have since withdrawn their complaints and are working towards a reconciliation.
