Jessica Simpson has been long rumored to be jealous of fellow music star Carrie Underwood, who previously dated Jessica’s BF Tony Romo, and In Touch Weekly is reporting that the feeling may be mutual. According to a new report from the celebrity weekly, the blonde beauties refused to appear anywhere near each other during last week’s CMA Music Festival (June 5-June 8) in Nashville, even though event organizers tried to create a united front between the ladies:

“They wanted Jess to introduce Carrie, or have them attend a charity event together, or maybe even do a duet to put the rumors to rest about the feud,” an In Touch insider says. “But everything was thrown out there was rebuffed.”
