Los Angles, Oct 11 (IANS): Actress Kaley Cuoco and Ryan Sweeting reportedly had screaming fights, daily before their split after almost two years of marriage.

The “Big Bang Theory” actress who officially filed for divorce from the professional tennis player Ryan Sweeting, citing "irreconcilable differences" had been getting into screaming fights with Sweeting almost everyday, reports femalefirst.co.uk.

"She may seem like America's sweetheart, but it's actually quite the opposite. She can be a real nightmare at times and incredibly difficult to deal with,” InTouch Weekly magazine quoted a source as saying.

"She's always been very moody and gets mad at everything. It's affected almost every relationship she's ever been in. These last couple of months have been brutal and extremely tense. Ryan and Kaley were having screaming fights daily - it really just got to be too much,” the source added.
