An omg! source confirms they were being affectionate but "not too crazy," and that Daniel was in a very jovial mood.
"He was the last to leave, and so happy," the source said of Daniel, who showed off some dance moves and enjoyed cocktails through the evening.
"They've been dating for a while but have been debating going public," one partygoer familiar with the pair told People.
Radcliffe split from his production-assistant girlfriend Rosie Coker in October 2011.
"Darlings" also stars Lizzie Olsen, Ben Foster, and Kyra Sedgwick.
