Big Bang Theory's Kayley Cuoco and Karl Cook announce separation

Big Bang Theory star Kayley Cuoco and husband Karl Cook have called it quits after three years of marriage. 

The couple announced on Friday that they will be going their separate ways, but insisted there's no bad blood. 

In a joint statement issued to People magazine, Kayley and Karl said, "Despite a deep love and respect for one another, we have realised that our current paths have taken us in opposite directions.

"We have both shared so much of our journey publicly so while we would prefer to keep this aspect of our personal life private, we wanted to be forthcoming in our truth together.

"There is no anger or animosity, quite the contrary. We have made this decision together through an immense amount of respect and consideration for one another and request that you do the same in understanding that we will not be sharing any additional details or commenting further."

Kayley, 35—who was previously married to Ryan Sweeting—and Karl, 30—a professional equestrian—met back in 2016 and got engaged the following year. 

They tied the knot in an intimate ceremony in California in 2018.

The shock announcement comes just two months after the couple marked their anniversary on Instagram, with Karl wishing for "a million more years".

In a sweet tribute to his wife, he wrote, "I agree @kayleycuoco I am just as amazed it's been three years, feel like just a flash. I love you so much and I can't wait for a million more years."

While it's unclear which "different directions" the couple are referring to, Kayley has been hard at work filming a new movie, Meet Cute alongside Pete Davidson. 

Their marriage hasn't always been entirely conventional as the couple weren't living together when they got married. 

"We have a very unconventional marriage, you know," she previously said. "We have different locations that we're at a lot. We're not together every single day."

They finally moved in together in 2020 in response to the covid-19 pandemic.

"This quarantine has actually forced us to move in together, it's been great for our relationship," Kayley revealed. "And we like each other, we realized! Which is even better."
