One of the stars of the Fox comedy series "That ’70s Show" has died. Entertainment Weekly reports that it has confirmed actress Lisa Robin Kelly, who played Eric’s older sister Laurie on the first five seasons of the show, is dead.

"Kelly passed away last night at a rehab facility, her agent, Craig Wyckoff, tells EW," the story reports. "The 43-year-old had voluntarily checked into treatment, ‘where she was battling the addiction problems that have plagued her these past few years.’ (Most recently, she was arrested on suspicion of drunken driving this past June.)"

Wyckoff said in an email to the publication: “I spoke to her on Monday and she was hopeful and confident, looking forward to putting this part of her life behind her. Last night she lost the battle.”

Kelly struggled with alcohol-related problems and a series of encounters with law enforcement, including a number of DUI arrests and allegations of spousal abuse.

TMZ.com reports that she died in her sleep Wednesday night. "We’re told Lisa’s new boyfriend brought her to rehab again on Monday … but she went into cardiac arrest late Wednesday night and could not be saved," the story reports.

TMZ adds: "Sources tell us Lisa had been in and out of rehab centers hoping to kick her alcohol problem … and most recently fell off the wagon after a huge dispute with her estranged husband Robert Gilliam. Sources say … Kelly’s estranged husband beat her last May to obtain residual money from her show. He was convicted of domestic battery last month and sentenced to 3 years probation. He also served 35 days in jail for the beating."

Kelly reportedly filed for divorce from Gilliam last month.
