Rumer Willis' nickname, "Rue," can be heard on the 911 call that was made when mom Demi Moore was suffering a seizure after "smoking something" -- and on Tuesday a source was confirming that Rumer was indeed present during the emergency.
With "a few people" still around from a birthday party Demi had been hosting, Rumer and a couple of friends were in another part of the house when the seizure occurred, a source told E! News.
According to the 911 call, which had specifics about substances edited out, Moore had "smoked something" that was "not marijuana, it's like incense." (Hear the full 911 call, placed on Jan. 23, below.)
Speculation about what she might have smoked has included mention of "spice" or "K2" and other herbal incense products, which are often laced with designer drugs and can "quite often" result in seizure activity, according to a doctor who spoke with ABC News. Salvia, which has hallucinogenic effects, is also sometimes marketed as herbal incense.
While Moore's whereabouts remain uncertain, Willis on Sunday night hit the official gala after the Screen Actors Guild Awards with Annie Starke, Glenn Close's daughter.
Keeping it low-key, Rumer greeted same-aged thesps, including cast members from "Glee," staying tight with her friend and stargazing.
