Avril Lavigne: Girls' Night Out at Chateau Marmont!

Avril Lavigne links arms with two gal pals while leaving Chateau Marmont on Wednesday (April 11) in Los Angeles.

Last month, the 27-year-old pop star visited her Avril Lavigne Rockstar Club at Easter Seals in southern California where she danced and sang karaoke with kids participating in the program.

“Dear Avril, I just want to thank you for your commitment to helping children with disabilities and your work with Easter Seals. The Easter Seals program has been vital for my son to have after-care once school is over,” one mom named Corky wrote to Avril.

“My son, Timmy is nonverbal and has autism. Since 6 [months old] he has always responded to music,” she added. “He can read and is absolutely mesmerized and motivated by the karaoke machine. Thank you again for improving the quality of my son’s and all of the children’s experience at Easter Seals.”
