Actress Paz de la Huerta has denied she was boozing at director Brett Ratner's party on Monday after she was involved in a dispute with a pal.

The Boardwalk Empire star reportedly got into a scuffle at the Stone Rose Lounge bash in New York after she accidentally spilled a drink over her friend, who broke down in tears and refused to accept de la Huerta's apology.

The incident sparked rumors the star was drinking again following her run-in with the law earlier this year, when she was sentenced to community service and 12 weeks of alcohol counseling after allegedly punching a partygoer at a Big Apple club.

However the brunette is adamant she hasn't touched a drop since March, and blames the dispute on her friend's intoxication and emotional issues.

She tells New York Post gossip column PageSix, "I haven't had a drink since March 23. I was drinking Coca-Cola. I brought a very good friend to the premiere who's having problems. She got wasted. She lost her wallet and was screaming and wailing and acting irrational. She spilled a drink on herself when I reached over to hold her hand to calm her down."

"She feels horrible about it. I made the decision to leave. Brett is a dear friend."
