Looks like Chris Rock approves of Rihanna's gorgeous gown as the two arrive at the Gucci charity event at the United Nations in New York Wednesday night. The singer wasn't the only one getting checked out. The soirée – hosted by Madonna and bringing in $3.7 million for UNICEF and Raising Malawi – was a star-studded one including A-listers Jennifer Lopez, Katie Holmes, Tom Cruise, Gwyneth Paltrow and Salma Hayek.

Most were wearing Gucci and you can check out their head-to-toe ensembles in PEOPLE's photo gallery.
