The Alice+Olivia summer concert benefiting kicked off Saturday night at Surf Lodge where guests including actress Michelle Trachtenberg, and Montauk regulars Alexandra Richards and DJ Francesco Civetta relaxed on the outdoor deck as Alexa Ray Joel took to the stage with mom Christie Brinkley filming from the sidelines. The former supermodel might possibly be the coolest stage mom in Montauk and took no chances of stealing the spotlight away from her daughter. She wouldn't even jump into a pic with Alexa, Alexandra, and Michelle when asked exclaiming "not with 3 gorgeous girls like that!" The evening benefited The Art of Elysium, a non-profit organization founded in 1997, that encourages working actors, artists and musicians to voluntarily dedicate their time and talent to children who are battling serious medical conditions.
