Reality-TV performer Samantha Swetra will file a civil lawsuit against HBO actress Paz de la Huerta as early as today.

Swetra’s lawyer, Stephanie Ovadia, said the suit will allege that de la Huerta assaulted Swetra at the Boom Boom Room in Manhattan last month.

The two actresses were at The Standard hot spot on Washington Street on March 20 at 4 a.m. when de la Huerta allegedly began cursing and threatening Swetra, who was hanging out with Lindsay Lohan.

“I’m a real actress on HBO! She’s a fake-actress publicity-seeker!” de la Huerta sniffed to cops when nabbed for assault.

An apparently intoxicated de la Huerta was seen stumbling that night, her breasts popping out of her low-cut top, a witness said. She allegedly pummeled Swetra with her fists and smashed a glass on her.
