Just in time for Valentine's Day, Daniel Craig and Rachel Weisz are getting hot and heavy!

After very quietly going public with their romance in the English countryside over Christmas, the sexy British stars ramped up their PDA on Monday in NYC, hitting the anniversary party for hotspot The Box.

At the A-list fete (also attended by Josh Duhamel, Fergie, and Adrian Brody), the duo shared a table with Hugh Jackman and wife Deborra-Lee Furness plus actor Alan Cumming. Sipping champagne, Craig and Weisz were "making out and dancing all night," a witness tells UsMagazine.com.

"They were adorable," adds the observer. Once the band Scissor Sisters began playing, the couple -- onscreen lovers in the upcoming film Dream House -- left their table and "started dancing...and they were kissing!"

After eight years together, Oscar winner Weisz, 40, announced her split from Black Swan director Darren Aronofsky in October of last year; they share a 4-year-old son, Henry. For his part, 007 star Craig, 42, reportedly broke up with longtime girlfriend Satsuki Mitchell in early 2010.
