That 70’s Show star was not taking any withdrawal drugs at the time she died, according to the rehab facility where she was staying.

According to TMZ, L.A County Coroners went to Pax Rehab House in Altadena, California on Thursday afternoon where they were told Lisa Robin Kelly wasn’t given any drugs.

Lisa Robin Kelly’s death seems mysterious as there were “no drugs or alcohol in her room, no vomit in her airway and no obvious sign of trauma”.

Her spokesman confirmed her death to TMZ on Thursday saying: “She had been fighting demons for a while and finally lost her battle.”

Lisa Robin Kelly’s manager, Craig Wyckoff, told FOX411 he had spoken with the troubled star on Monday and she was “hopeful and confident, looking forward to putting this part of her life behind her”.

Craig Wyckoff also confirmed that she had voluntarily checked herself into the centre after being in and out of treatment facilities for alcohol addiction – she vehemently denied taking drugs – trying to get on the road to recovery.

Lisa Robin Kelly is reported to have fallen off the wagon following a huge dispute with her estranged husband, Robert Gilliam.

“She was battling the addiction problems that have plagued her these past few years,” Craig Wyckoff said.

He added: “Cause of death has not been issued yet and no death certificate has been issued either.”
