Someone better tell Nicole Fiscella (aka Isabel Coates, a member of Blair's entourage on Gossip Girl) that you're not supposed to spread gossip about your co-star! The actress confirmed to People that Chace Crawford is, in fact, dating Carrie Underwood! "They're the cutest couple," Nicole says. "Chase is just such a great guy. He's so fun and I think he just loves his life right now. He seems to be having a good time with [Carrie]."

But Nicole has yet to actually meet Chace's off-screen GF. "We were all going to meet up one night and I didn't get to meet her yet," she says. "But I hear she's a great girl." Um, we doubt she's gonna be meeting her now! Good job, big mouth.
