New reports have claimed that Kaley Cuoco's behavior was the true reason behind her split from Ryan Sweeting, but it appears those rumors are extremely false. 

Is Johnny Galecki The Love Of Kaley Cuoco's Life?

In Touch reported that the Big Bang Theory actress was the one to blame for her marriage's end after 21 months because she was a "nightmare behind closed doors" who lead a "double life." 

"She may seem like America's sweetheart, but it's actually quite the opposite. She's hot-headed  and argumentative," sources said to the magazine. 

Ryan Sweeting Reportedly Knew Kaley Cuoco Was Filing For Divorce For A 'Long Time'

The source also went on to say that previous reports that Sweeting had a drug problem were false, and the actress had a major drinking problem instead.  

"Kaley would go out with her friends, without her wedding ring, and get wasted," the source said.  

Her drinking was reportedly so out of control that she would drink two bottles of wine and call Sweeting for a ride home-but whenever he would go to pick her up she would "lash out and curse at him," because she was "very moody and gets mad at everything."  

However, sources close to Cuoco have told Gossip Cop that the rumors are ridiculous and completely untrue, and that those are not reasons contributing to her divorce.  

Cuoco and Sweeting married in a New Year's Eve ceremony back in 2013, just six months after they began dating. They were plagued with split rumors throughout their marriage, which they often spoke out against. The divorce was announced on Sept. 25.
