'Big Bang Theory' star Kaley Cuoco gets hitched to longtime boyfriend Karl CookJuly 1 (AZINS) The Big Bang Theory star Kaley Cuoco tied knots with longtime boyfriend, Karl Cook.

The couple celebrated the ceremony with their family and friends in a summertime ceremony in San Diego, confirmed E!Online.

Taking to Instagram, the star posted a black and white snapshot of the couple kissing.

She captioned the image as, "Legally KCSQUARED 6-30-18."

For the ceremony, Cuoco wore a white lace gown with matching cape. She later changed into a jumpsuit and switched her elegant low bun into a high ponytail.

Cook proposed to the actress on her 32nd birthday i.e. seven months ago.

Cuoco and Cook first sparked romance rumours in March 2016. A month later, Cuoco posted a cozy picture of her with her boyfriend on Instagram, saying, "That's what happy looks like."

In September 2016, they made their relationship red carpet official.

After Cuoco accepted the proposal, the newly engaged couple slow danced to Ed Sheeran's song 'Perfect.'

Cuoco, who was named the second highest-earning TV actress in the world by Forbes this year, was previously married to tennis player Ryan Sweeting; the pair finalised their divorce last May.

"You know what, I'm not ashamed of anything that happened. I fall in love really hard, I do. I go deep. That person is it for me. And I love hard, and when it's over, it's over, and some people make mistakes. (I) wouldn't call it a mistake, it just is what happened in my life, so I'm excited to see what the future holds. It happened, and now I have to say I'm happier than I've ever been," Cuoco had said after the divorce.

She also dated her The Big Bang Theory co-star Johnny Galecki for a brief time.
