Gossip Girl Star: Chace & Carrie are the Cutest!

While the lovely Blake Lively has yet to comment on the budding relationship of Chace Crawford and Carrie Underwood, another Gossip Girl co-star, Nicole Fiscella, can't say enough good things about the new romance.

Chace Crawford "is having a good time" with Carrie Underwood, according to Fiscella, at Tiffany & Co.'s Blue Book Collection launch Saturday.

"They're the cutest couple," Fiscella says of Crawford and Underwood, who have been spotted hanging out around New York City in the last month.

The pair has been hanging out and stopping everywhere from the hip hot spot Marquee to Justin Timberlake's Southern Hospitality restaurant.

"Chase is just such a great guy," Nicole Fiscella, 23, says of her 22-year-old Gossip Girl co-star.

"He's so much fun and he just loves his life right now. He seems to be having a good time with [Carrie]."

Underwood, the 24-year-old American Idol winner, who finds Crawford "really cute," has plans to meet Chace Crawford's Gossip Girl costars soon.

"We were all going to meet up one night and I didn't get to meet her yet," says Fiscella, "But I hear she's a great girl."

We would have to agree. Tony Romo, you missed out.
