Jennifer Lopez and Marc Anthony's Carousel of Hope

Never ones to shy away from pitching in for a good cause, Jennifer Lopez and Marc Anthony dazzled at the Beverly Hilton Hotel in Beverly Hills, CA on Saturday night (October 23).

The "Backup Plan" babe looked breath-taking in a sparkly white Georges Chakra frock as she joined her tux-clad hubby at the 32nd Anniversary Carousel Of Hope Gala.

Not only there as attendees, J Lo (who changed into a Zuhair Murad dress) and Marc took the stage during the course of the evening to treat fans to a rendition of their energizing musical offerings.

Fellow celebrity guest Paris Hilton tweeted of the performance, “Jennifer Lopez and Marc Anthony just performed at the event. J Lo looked amazing as usual, she is absolutely stunning! I am obsessed with the dress she’s wearing. Love her!”

As for the festivities, the Carousel of Hope Gala is held every other year while benefiting the Barbara Davis Center for Childhood Diabetes.
