Amy Adams paraded around in lavender hair extensions while LL Cool J ponied up eight grand for a guitar signed by the Red Hot Chili Peppers at Sunday’s John Varvatos’ 11th annual Stuart House benefit. “I’m happy to contribute,” LL Cool J said, adding, “I would have given the money for nothing … As a child growing up I experienced abuse in my life on certain levels and this is something that is near and dear to my heart.”

Varvatos said he got involved a decade ago when he met some young children at the Santa Monica Rape Treatment Center. He decided then that it was about time men got involved in the cause that had traditionally been championed by women. “It is a cause that needs greater awareness. We all have children we are connected with and we want to protect them,” he said.

Adams, a co-chair of the event, said she has visited the Stuart House and found “the work they do there is impressive, it is compassionate, it is comprehensive and they pay attention to so many details (including) the privacy, the safety (of the children). And they have a 24 hour a day ER devoted exclusively to children.”

Also on display at the Melrose Avenue store was the 2014 Chrysler 300C John Varvatos edition which retails for $60K. Klaus Busse, head of interior design for Chrysler, said of the car: “The exterior is the love affair and the interior is the wedding.”

Hasbro hosted an impressive children’s tent with spectacular balloon creations, hair stations, air hockey, magic shows, videogames and giant Jenga for all to experience.

For the adults, a silent auction was topped off with a performance by Willie Nelson & Sons. Nelson can be seen in the current Varvatos ad campaign.

Other guests included Jessica Simpson, Rachel Zoe, James Van der Beek, Kat Graham and Joe Manganiello.
