EXCLUSIVE VIDEO INTERVIEW: Grease Star Jeff Conaway Tells Radar: My Ex Fiance Injected Me With Painkillers, Planted Cocaine Before Cop Bust

Grease actor Jeff Conaway says he has a new role, but not one he wants: elder abuse victim.

The 60-year-old star, who played T-Bird Kenickie in the classic 1978 film, was granted court protection from his ex-fiance of seven years, Vikki Lizzi, after he filed a case against her charging she injected him with painkillers and planted cocaine in the Los Angeles house they shared before attempting to orchestrate a police bust.

Conaway also alleged Lizzi, real name Victoria Spinoza, has stolen thousands of dollars and forged his signature on bank checks.

Speaking to RadarOnline.com, Lizzi denied planting any drugs on him and laughed off her ex's allegations.

"I can't help laughing because it's funny to me and that's what this thing is all about, is the fact that he's on so many pain meds that it's affecting his mental state, all these things that he's making up," Lizzi told RadarOnline.com.

In her own court claim, Lizzi sought and won her own restraining order after she claimed the Taxi star pulled out a knife and a hammer and threatened "he was going to ruin my life."

"The reason I got the restraining order is because he came at me with a hammer and scared the living daylights out of me," she said.

"Right now, I don't feel safe, I'm scared at night.

"I'm scared during the day that there's going to be some kind of, you know... he's gonna do something. He's a just loose cannon."

Lizzi also claimed dad-of-one Conaway, who was previously married to Grease co-star Olivia Newton-John's sister Rona, attempted to blackmail her and even made marks on his arms and claimed she had done it to him.

Conaway has battled substance abuse issues for years, having appeared on Celebrity Rehab in 2008 and admitting his addiction to painkillers and alcohol.

The actor, who starred as out-of-work actor Bobby Wheeler in the comedy series Taxi, even suffered a near fatal freak fall last year leading to a brain hemorrhage, fracturing his neck and breaking his hip.

Despite their legal standoff, the former lovers each had concern for their ex's welfare.

A tearful Lizzi handed her one-time beau a single white lily and said she hoped he would enter a rehab detox program immediately.

"I really wish he would because I would like to have him back as a friend one day just to be able to see that normal, sweet, caring Jeff again," she told RadarOnline.com.

"I've been grieving and that flower is my grief; my hope to him is that there can be peace one day."
