Since their romance jumped out of the gates in October with a smooch-filled weekend in NYC, country superstar Carrie Underwood and Gossip Girl stud Chace Crawford have only been seen together a handful of times — never at red-carpet functions — and rarely answer questions about their couple-dom.

And OK! has learned that it’s not just the public that’s being kept in the dark about this camera-friendly couple. Even Chace’s Gossip Girl co-star Kelly Rutherford is curious. "I’ve never seen her on the set,” she tells OK! at the Readalicious Wonderland event in Century City, Calif., on March 1. “He’s keeping her a secret!”

And even though Kelly hasn’t had the chance to chat up Chace’s cutie-pie, she does have one request to make of her 22-year-old co-star and his gal-pal: “I hope she sings for the show!”
