For the first time this year, the weather is truly steamy in New York.

But for fan favorites Leighton Meester and Ed Westwick, turning up the heat on the set of Gossip Girl is nothing new. In fact, they've got it down to a science.

The couple filmed scenes for the hit show today as their alter egos Blair Waldorf and Chuck Bass, and the show's hottest couple gave us plenty to look forward to ...

CHAIR-ISH IT: Finally a couple after two years of pining for one another, Chuck and Blair look to be making up for lost time in the first few episodes of the third season.

In addition to Chair kissing, co-stars Blake Lively and Penn Badgley (a real-life couple even if Dan and Serena aren't) and guest Joanna Garcia were also seen on set.

As always, when we see pictures from the set, we pass them along for your anticipatory pleasure. Click to enlarge lots more (hot!) Gossip Girl pictures from today ...
