Queen Latifah, Zac Efron, Amanda Bynes and others – conversing in a sing-song manner over a meal at West Hollywood's Koi. According to an onlooker, the group started talking in "high-pitched, musical voices, questioning and answering each other." The friendly bunch couldn't stay in tune for too long, though. They kept bursting into laughter, the onlooker tells us.
Sounds like fun!
