Big Bang Theory star Kaley Cuoco and husband Ryan Sweeting's marriage may soon crumble, according to reports.

The latest rumor about their alleged impending divorce claims that the couple had a big fight and was having trouble reconciling, a report by the Inquisitr noted.

As stated on Celeb Dirty Laundry, "Friends of the couple are whispering that their dysfunctional marriage is about to crumble into divorce because of their bad behaviors and vicious cycle of tit-for-tat. Kaley is the jealous type and is very needy in relationships. Ryan played along in the beginning but between Kaley's inflated ego and his insecurities, he is beginning to rebel."

"Ryan gets upset that Kaley expects Ryan to be around constantly, and she gets upset when he chooses to go out with friends instead of her. She drinks to drown her sorrows, but always ends up screaming at him, then later crying as she apologizes for getting upset. Ryan cannot take the erratic behavior. It has gotten to the point where Ryan doesn't even go out anymore because he doesn't want to deal with the drama," Celeb Dirty Laundry added.

Inquisitr cited a report by Star Magazine, noting that allegedly, Sweeting is tired of Cuoco's "erratic behavior," prompting him to sleep in the guest room.

"She's started bossing Ryan around and treating him like a houseboy," a Star Magazine source claimed, as reported by Inquisitr. "They've been fighting a lot because he tells her she's not a star at home."

However, International Business Times maintained that the divorce rumors are only that: a rumor. On Halloween, Cuoco slammed the issue by posting a photo on Instagram of her and Sweeting dressed up as on-again off-again couple Justin Bieber and Selena Gomez. The couple reversed genders; Cuoco went as Bieber while Sweeting dressed in drag by playing Gomez.

The reps of "The Big Bang Theory" star denied the couple's separation. "The actress even had her wedding date tattooed on her back, between the shoulder blades, to prove her love for Ryan Sweeting," International Business Times wrote.

Cuoco wore her pink Vera Wang wedding dress again for her upcoming movie titled "The Wedding Ringer," Yahoo reported. On her Instagram account, Cuoco posted behind-the-scenes photos of her wearing the dress while filming the movie. International Business Times pointed out that this is the actress's act of defiance for people who claim that she is about to divorce her husband.

Cuoco first wore the wedding gown when she walked down the aisle on December 31, 2013, to wed tennis player Sweeting in front of 150 friends and family at the Hummingbird Nest Ranch in Santa Susana, California, Yahoo noted.
