“Don Felder performing ‘Hotel California’ w/Crosby & Nash backing him up-a radical moment at the #autismspeaks event,” Kristen tweeted.

Proceeds from the concert will go towards Autism Speaks’ research and advocacy efforts for families and individuals impacted by the disorder.

Earlier in the week, Kristen donned a sexy sheer dress while attending American Express #EveryDayMoments held at Home Studios in New York City.

FYI: Kristen is wearing an Alberta Ferretti dress and Christian Louboutin shoes. Christina is wearing a Diesel Black Gold skirt, a Rag & Bone blazer, and Pluma bracelets.
