(LOS ANGELES) -- Lindsay Lohan may have been at a Screen Actors Guild after-party on Sunday night, but she insists she was not drinking there. TMZ.com reports that the Mean Girls star is so upset over rumors that she was drinking at the party, held at the West Hollywood luxury hotel Chateau Marmont, that she's threatening legal action against the media outlets that published them.
RadarOnline.com reported this week that Lindsay "appeared to be under the influence" at Chateau Marmont and was seen entering a bathroom frequently with a male companion.
"She appeared to be loaded on something," a source said.
According to TMZ, Lindsay claims she only drank water at the party, and was with actor Alan Cumming throughout the night. She also denies other speculation that she recently made out with Dennis Hopper's son, Henry, at a gas station.
TMZ reports that Lindsay, who is currently on probation for previous DUI and theft convictions, is exploring her legal options because she believes the reports are damaging her potential acting comeback.
TMZ has stated that Lindsay is temporarily living at Chateau Marmont after moving out of her Venice Beach, Calif., home.
