It looks as though LeAnn Rimes' 'sicknesses' might finally be explained. There is a new report that suggests the country singer has been canceling her concerts not because she's been sick, but so that she can keep an eye on her husband Eddie Cibrian.

According to Star Magazine's print edition on Thursday (via Celebitchy), the former chart topper has infuriated her fans by canceling so many of her tour dates in the last several weeks, but sources close to the blonde beauty say that she's been doing so because she is scared Cibrian might cheat on her.

An insider told the magazine, "She figures that if she watched over Eddie's every move and spends every waking moment with him, there'll be no way for him to have an affair. Her fans may hate her for it, but she couldn't care less."

Just recently, the singer was accused of "canceling more concerts than she performs" as she once again canceled several more weekend concerts due to her poor health.

According to The Las Vegas Review Journal, Rimes was scheduled to perform at several casinos in Sin City but pulled the plug on her performances last Wednesday.

Many readers of the site couldn't help but comment with, "She cancels more concerts than she preforms. I don't know how she keeps getting booked at anything," along with, "I think she is suffering from that disease that affects all has-beens called 'low-ticket-sales-itis.'"

Another commenter wrote, "People all over Twitter predicted this days ago! Leann does this kind of stuff all the time. She is afraid to let her husband out of her sight! It's pathetic and her marriage is a farce! I stopped being a fan to her music years ago do to her constant vile behavior."
