Carrie Underwood and Chace Crawford have split, sources told Usmagazine.com.
The "American Idol" winner, 25, and the "Gossip Girl" star, 22, had been dating since last July, but did not go public with their romance until October.
Underwood spent Thanksgiving at his parents' home in Dallas and part of her Christmas break with his relatives, Usmagazine.com reports.
An insider told Us Weekly in December, "His parents are fond of her ... they believe 'Carrie Crawford' would be a great addition to the family!"
"She's a classy girl," Crawford told Us in October.
Rumors linking Crawford to buddy JC Chasez sparked Chasez to tell Kiss-FM 104.7 Wednesday, "For the record, we're both straight. We're not dating."
