We feel a lot like Gossip Girl right now, typing away furiously in order to make sure this rumor spreads across the computer screens of all fans:

According to OK! magazine, Chace Crawford is dating American Idol champion Carrie Underwood. The two were spotted locking lips last Friday at NYC club Marquee.

"They were canoodling all night and stayed until close," said one witness.

The following evening, the couple was spotted at Mario Batali's Del Posto restaurant, the Soho Grand and the Rose Bar in the Gramercy Park Hotel. That's a lot of eating and drinking for one weekend. Should Leighton Meester feel betrayed?

At the Soho Grand, "they held court at their own private table, kissing and not leaving each other's side," the source added.
