Carrie Underwood and Chace Crawford appear to be much more than a fling.

"His whole family loves her," a friend of the couple told Us Weekly. "They are really perfect for each other."

Just how close is this couple? After the American Idol winner spent Thanksgiving with the Gossip Girl star at his parents' home in Dallas, she joined his relatives on part of her Christmas vacation, too.

"They spent Christmas together and had a wonderful time," a source reported.

Underwood, meanwhile, has no regrets about her July split from Tony Romo, the tabloid also said.

"She thanks her lucky stars she isn't with Tony anymore!" said a 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.'"

It's hard to argue with those assessments, isn't it?
