Rachel Weisz took a walk in NYC with her ex-fiancé, Black Swan director Darren Aronofsky, yesterday in NYC. The former couple have put on a united front since splitting last year, staying close for the sake of their son Henry. She stayed behind in the Big Apple as her current flame, Daniel Craig, jetted across the country and landed in LA. Rachel and Daniel were apparently side by side to show some love on Valentine's Day by dancing and kissing the night away at The Box. It was their latest holiday together, after being snapped in England around Christmas. Both Daniel and Rachel, who star in the upcoming drama Dream House, will be busy in the coming months with their careers. Daniel will be back on set shooting the next James Bond, and there are rumors Rachel may even join the production as his onscreen enemy.
