A new report claimed LeAnn Rimes and her husband Eddie Cibrian did not attend the 2013 CMA Awards because of her recent weight gain.

Rimes reportedly declined to attend the country music ceremony, which was held at the Bridgestone Arena in Nashville, Tenn. on Nov. 6, because she gained 38 lbs. An insider alleged she has been overeating due to stress from dealing with marital problems with Cibrian. 

"Poor LeAnn is so distraught over fears that Eddie is going to cheat on her that she's drowning her emotions with junk food... she's gobbling everything in sight," a source told National Enquirer. "Now she's become so self-conscious that it kept her from attending the CMAs. She feels physically unattractive and didn't want to try to squeeze into a formal gown."

Rimes is currently 5 feet 6 inches tall and reportedly weighs 128 lbs., but she usually weighs less. Reports once claimed she was suffering from anorexia because in the past, she was below her average weight.

"LeAnn is worried sick because she knows the type of woman that catches Eddie's eye," the source also shared. "And right now she's a far cry from that."
