"Big Bang Theory" Season 8 cast Kaley Cuoco and Ryan Sweeting divorce rumors loom as they were reported to have been fighting in an HBO afterparty recently.

According to The Epoch Times, the "Authors Anonymous" actress and her tennis pro husband Ryan Sweeting were said to be fighting with each other as eyewitnesses said they were both "very angry."

Life & Style magazine's source said that the two, who have been married for eight months, were into each other's throats.

"They get into these knockout, drag-out fights," the insider revealed.

Another source added, "Kaley was shaking her head, turning red. She looked like she was going to cry."

The insider explained that the "Big Bang Theory" Season 8 cast Kaley Cuoco was drinking rose and was heard saying "Please don't leave me" to her tennis player husband.

The actress later got up to the bathroom and Ryan Sweeting was spotted putting his finger to his head as if shooting himself twice.

But a source close to the actress debunked the Kaley Cuoco and Ryan Sweeting divorce rumors as reported in Perez Hilton blog.

"This is a ridiculous attempt by tabloids to grab a headline and is not at all based in reality," the source told Perez Hilton.

Aside from Kaley Cuoco and Ryan Sweeting divorce rumors, the actres also faced another controversy last week.

The "Big Bang Theory" Season 8 cast Kaley Cuoco was among the Hollywood celebrities, who were on the list of the alleged mass nude photo leak scandal that was released in websites 4chan and Reddit.

When news broke last week that certain stars including Jennifer Lawrence, Kristen Dunst, Kate Upton and Selena Gomez have been involved in the nude photo leak, "Big Bang Theory" season 8 cast Kaley Cuoco just laughed off the rumors by posting a funny Instagram photo.

Showing a photo of Kaley Cuoco and Ryan Sweeting walking at the beach with their body parts obviously blurred, the actress said in her caption, "What a fun day that was, frolicking with my hubs on the beaches of Mexico! Feels like we forgot something?"
