Chace Crawford is crazy about Carrie Underwood.

Apparently, so is the Dallas native's entire family.

"His whole family loves her," a friend of Chace Crawford and Carrie Underwood tells Us Weekly. "They are really perfect for each other."

How close are the adorable Idol / Gossip Girl duo of six months - who started dating in July but didn't go public until October, and are still pretty coy about it?

After the fourth season American Idol winner and Oklahoma native, 24, spent Thanksgiving with the Gossip Girl hottie, 22, at his parents' home in Texas, she joined his relatives on part of her Christmas vacation as well.



"They spent Christmas together and had a wonderful time," a source says. "His parents are fond of her and think she's extremely talented. And they certainly believe Carrie Crawford would be a great addition to the family!"

Carrie Underwood, meanwhile, has no regrets about her July split from Tony Romo, the Dallas Cowboys star who is now dating Jessica Simpson.

"She thanks her lucky stars she isn't with Tony anymore!" added the insider Us source. "She thinks it's a joke he's with Jessica Simpson and sees him as a player. Carrie and Chace call him 'the player' and Jessica 'the ditz.'"
