It was one of the first comfortable summer evenings in Manhattan following a brutal heat wave.
Until Daniel Craig and Rachel Weisz showed up, that is.
After the Cinema Society & Dior Beauty screening of The Whistleblower, the newlyweds made their first public appearance as a couple, heating things up with a very public rooftop smooch.
“When Daniel arrived on the roof deck, he embraced Rachel and gave her a long tender kiss on the lips – it was very romantic,” a source at the James Hotel after-party tells PEOPLE.
“I wanted to be part of that kiss,” says an onlooker. “It was very hot,” added another.
Weisz, 41, and Craig, 43, were wed in a secret ceremony in New York in June.
