Jennifer Lopez celebrated her new album LOVE? with a CD signing held at the Hard Rock Cafe Hollywood on Tuesday (May 3) in Hollywood, Calif.

The 41-year-old American Idol judge signed a guitar exclusively for a Art Project Los Angeles benefit. The event is a red-carpet charity art auction and artists reception, a benefit for APLA, which provides life-saving care for thousands of Angelenos living with HIV/AIDS.

The red carpet event, VIP cocktail party and live charity auction, takes place on Friday, June 24.

FYI: Jennifer is wearing Elie Saab black jersey trousers and H. Stern jewelry.
