Carrie Underwood had quite a lot to say to Allure when she sat down with them for their September issue!

Aside from talking about her romance with Gossip Girl star Chace Crawford - "No one cheated. It plain didn't work," she says - the country queen ALSO chatted about Tony Romo, Jessica Simpson's current flame...

"We relied on each other, dealing with fame," explains Carrie. "I don't know. The phone will ring and it'll be him, and I'll maybe not answer."

Ouch! Does Jess know about this? And is this why she wore that T-shirt a while back?!?
