LeAnn Rimes and Brandi Glanville called their Twitter truce after the country singer and her fiancé Eddie Cibrian finally shelved plans for a newly weds reality show, RadarOnline.com can reveal.

The two women have a long history of feuding since CSI Miami star Cibrian walked out on his wife and mother-of-his-two sons to be with Rimes.

However, the former love-rivals took to Twitter over the weekend to announce that they are ending hostilities via the social network forum.

A source told RadarOnline.com: “They are trying to patch things up and it was big for Brandi when Eddie told her they had no plans to do a newly weds style reality show that had previously been widely reported.

LeAnn Rimes was recently photographed looking super skinny and in an effort to deflect public criticism, the singer took to her Twitter account in defense, RadarOnline.com has learned.

"Maybe it's time for a nude pic so peeps can see how I look nowhere near what these stupid pics are trying to make me look like, LOL #joke," Rimes tweeted on Tuesday.

"I don't care about the dumb articles. I know how healthy I am. Maybe those people should start taking care of themselves...inside and out."

Rimes jumped to the center of controversy when photographs emerged of her on Friday, March 11 walking around Calabasas, California with her fiancé Eddie Cibrian, looking noticeably thinner than she usually does.

"OVER It is right! I know how healthy I am, so really that's all that matters," Rimes responded to a fan via Twitter.

"I'm talking about the evil comments and the judging and rag mags."

Speculation rampantly grew online that the 28-year-old singer had dropped the weight for her impending nuptials to Cibrian, 37, but Rimes maintains that she's perfectly healthy.

"It's sad how mean people in this world can be for no good reason," Rimes wrote.

Dressed in denim shorts and a baggy black t-shirt, the once toned performer had bony shoulders and stick thin legs on display.

Dr. Farid Zarif viewed the images of Rimes and compared them to ones of the performer from December of last year.

The health expert said: "Just as a lot of people have a propensity to gain weight others have the same ability to lose it too.

"There is definitely an apparent difference in her appearance and stress could be a factor with her wedding coming-up.

"A lot of women try to lose weight to look good in their wedding dress and somebody like LeAnn Rimes is under 'invisible pressure' to look a certain way for her fans also.

"In addition she is under more stress because she is constantly being followed by photographers and unlike the rest of us her appearance is constantly documented.

"It could be that she feels better and has more energy with her new shape and at this point I would not say the weight loss was alarming.

"If I was treating her I would find how many calories she was getting each day and make sure she was getting a healthy balance of protein, fat and carbohydrates in her diet."

In October the 28-year-old told Shape Magazine that she keeps herself in shape by boxing and circuit training.

Rimes got engaged to CSI: Miami star Cibrian in December and although they have not set a date it's understood that the singer has been busy planning their ceremony.

She told People recently: "It's kind of chill. We're taking it as it comes and planning as it comes.

"It's an exciting year and a lot to handle, but I've got a good man at my side. So he's helping.

"He really is the sweetest, most supportive man."

LeAnn Rimes received a sparkling $85K engagement ring from new love Eddie Cibrian after his child support payments to his ex-wife were slashed because Eddie’s income had dipped, RadarOnline.com has learned.

In an exclusive interview, model Brandi Granville has admitted the timing “wasn’t obviously the best” and said her relationship with Eddie and LeAnn Rimes had deteriorated in recent months. She also revealed that while LeAnn got the expensive ring, she has to give BACK money from her divorce settlement.
