Well, they were -- and now they're not. According to Usmagazine.com, the American Idol winner and Gossip Girl hottie have ended their nano-relationship. The couple, who were supposedly dating since July (saw them together, like, once) and had reportedly spent Thanksgiving and Christmas together, just couldn't seem to make it work.

Hmmm. Maybe that's because Chace is spending all of his time with former boy band-er J.C. Chasez? This super duo, conversely, have been seen everywhere together. But, J.C. swears that he and Chace are just good buds and nothing more.

“For the record, we’re both straight,” J.C. said on a radio program the other morning. "We're not dating."

Okay, but when J.C. takes Chace home for Passover I might say "I told you so."
