Chace Crawford and Leighton Meester warmed up a chilly New York as they filmed steamy scenes for the new series of Gossip Girl yesterday.

The actors - who play former Upper East side couple Nate Archibald and Blair Whaldorf - were snapped locking lips in a passionate embrace as snow fell around them.

The behind-the-scenes pictures have reignited rumours of an on-screen reunion on the show after almost a season apart.

Blair and Nate's romance went sour in the first season when Nate's best friend Chuck began meddling in their relationship and stole Queen B's heart.

And now in a familiar twist of fate Nate seems to back on the scene to win back what was originally his.

Stay tuned for more juicy Gossip Girl gos....
