“The Big Bang Theory” actress Kaley Cuoco and husband of two years, Ryan Sweeting, are heading for divorce.

According to Us Weekly, Kaley’s rep confirmed the split, stating, “Kaley Cuoco and Ryan Sweeting have mutually decided to end their marriage. They ask for privacy at this time.”

The couple has yet to reveal the reason behind the separation but rumors suggested there may have been infidelity and feeling of resentment between the two, Inquisitr reported.

Rumors suggest Cuoco may still have a connection with her ex-boyfriend and “Big Bang Theory” co-star, Johnny Galecki.

Just few days before the divorce announcement was made, Cuoco, who plays Penny in “The Big Bang Theory, denied any marital problems.

During her appearance on “Watch What Happens Live“, Kaley said she and her tennis star husband was perfectly fine with the relationship she has with Galecki, who plays her now husband, Leonard, in the CBS hit show.

Cuoco said, “We dated like five years ago, so I think everyone’s moved on. Johnny’s actually one of my best friends. It’s a situation that ended well, I understand sometimes it doesn’t.”

“Ryan loves him, Johnny loves him. It’s been a long time, so it’s great. I got lucky. It could have been horrible,” she added.

According to Celeb Dirty Laundry, there were also reports that Sweeting is resenting the way Kaley is treating him.

The site quoted a source saying, “They’ve been fighting a lot because he tells her she’s not a star at home,” allegedly because Kaley treats Ryan like a house boy.

Kaley and Sweeting tied the knot on December 31, 2013 after three months of dating.

In an interview with Cosmopolitan, Kaley admitted that it was a whirlwind romance.

“I admit it happened fast, but that’s who I am. When we met, I knew he was the one. [At my wedding], I felt like a rock star and a bad**s. What was amazing in that room, it was so full of love,” she said.

People magazine noted that rumors of trouble marriage have been swirling around Kaley and Ryan since April.
