Porn stars and custody battles sound like something that would turn into drama and it damn sure did for Jacksonville Jaguars star Marcedes Lewis. He has a five month old son with porn star Savannah Stern and last night he told her he is filing for full custody. That is when all hell broke loose.

Via TMZ:

Cops were called to the L.A. residence of Jacksonville Jaguars star Marcedes Lewis Thursday night — after his baby mama allegedly went berserk when she found out Lewis is gunning for sole custody of their child … TMZ Sports has learned.

Lewis has a 5-month-old son with porn star Savannah Stern — who decided to visit Lewis at his pad, which happens to be in a fancy private building in L.A.

We spoke with Lewis who tells us … Stern was served with court papers during the visit — informing her that he has filed official documents in an effort to obtain sole custody of their child.

Lewis says Stern began to flip out once she got served — and began yelling and screaming … to the point where building staffers decided to call police for help.

Law enforcement confirms … cops arrived to the scene around 9 PM and took an incident report but no one was arrested. We’re told Stern eventually left the building without further incident.

We reached out to Stern for comment — no word back.
