Matthew Underwood, former star of Nickelodeon’s Zoey 101, came to the rescue of a 4-month-old baby after its smacked-out parents crashed their car.

According ton TMZ:

A female driver cut across 6 lanes of traffic on a busy street and crashed into a tree. We’re told she passed out at the wheel with a syringe full of heroin in her arm, with her baby daddy passed out in the back seat. Their baby was in an unsecured car seat next to the father.

According to the police report … Matt saw the parents passed out, removed the infant — who was not injured — and had his brother call 911.

Matt also shot video of the scene before cops arrived. The mother later told cops she’d just bought heroin to try for the first time. The dad had a pill bottle full of Alprazolam (generic Xanax), a smoking pipe and a 2nd syringe laying next to him.

First time. Yeah, right.

Both parents were booked for child neglect and drug possession. The baby was turned over to a family member.
