Chace Crawford and Carrie Underwood have gone their separate ways

Chace Crawford and JC Chasez aren’t dating according to both of them.

But apparently Chace is on the market guys and girls, because he and Carrie Underwood have broken up according to reports.

The former couple had been dating since last July, but did not go public with their romance until October. 

No word yet on who dumped who.

Among speculative reasons being thrown out, are Chace’s penchant to party without Carrie and allegations that Carrie is upset about former beau Tony Romo’s reported upcoming engagement to Jessica Simpson.
