Rumer Willis reportedly attended a Screen Actors Guild Awards after party, less than a week after her mother, Demi Moore, was rushed to the hospital.
Moore, who has appeared thinner than usual in recent months, was taken to a Los Angeles medical center on Monday, January 23, after Los Angeles City Fire Department received a 911 call from her home.
A spokesperson for Rumer Willis had no immediate comment on a reports by Us Weekly and People magazine, which said on Monday, January 30, that the 23-year-old model and former "90210" actress attended a Screen Actors Guild Awards gala on Sunday night.
People magazine said Rumer Willis and Glenn Close's daughter, Annie Starke, "seemed particularly interested in checking out Brad Pitt and Angelina Jolie, making their way to the couple's area and watching as they were escorted out of the party," after which the actress dropped by celebrity hotspot the Chateau Marmont in West Hollywood.
An edited recorded of the 911 call made from Moore's home was released on Friday. An unidentified woman tells the dispatcher that "Demi" "smoked something. It's not marijuana but it's ... similar to incense. And she seems to be having convulsions of some sort." (Listen to the 911 call).
Rumer Willis has also not commented on reports that say she was one of several people who witnessed the event. Two women, who are not her, and a man are heard speaking to the dispatcher during the 911 call.
Moore's spokesperson had said after the event: "Because of the stresses in her life right now, Demi has chosen to seek professional assistance to treat her exhaustion and improve her overall health. She looks forward to getting well and is grateful for the support of her family and friends."
The actress' rep has declined comment about whether Moore is still hospitalized or whether her treatment program would take place inside a medical facility.
Moore, 49, announced in November that she had decided to end her six-year marriage to Ashton Kutcher, 33.
Her personal turmoil prompted her to drop out of the film "Lovelace." She was set to play feminist activist Gloria Steinem in the movie, which is about the life of porn star Linda Lovelace. On Friday, a spokesperson for the film told OnTheRedCarpet.com that Sarah Jessica Parker, 46, would take Moore's place.
Rumer Willis's father is Moore's ex-husband, actor Bruce Willis. The former couple also have two other daughters - Tallulah, who turns 18 on February 3, and Scout, 20.
