KALEY CUOCO and her second husband Karl Cook announced Friday that they’re going their separate ways after three years of marriage.

Their divorce proceedings will include their prenuptial agreement, Us Weekly confirms.

A source close to Cuoco, 35, revealed that the “Flight Attendant” star “has ironclad prenup in place.” The actress and Cook, 30, signed a legal agreement just in case they were to split.

The duo started dating in 2016, got engaged in 2017 and tied the knot in 2018. But they didn’t live together full-time for the first two years of their marriage, and in April 2020, Cuoco said that she and the professional equestrian might not have finally moved in together if it hadn’t been for the COVID-19 pandemic.

The Emmy nominee filed for divorce Friday — the same day the pair announced their breakup.

“Despite a deep love and respect for one another, we have realized that our current paths have taken us in opposite directions,” they said in a joint statement to Us Weekly on Friday. “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.”

“They were affectionate and seemed great,” a source told People. “The split seems very sudden. It’s pretty shocking.”

After Cuoco officially filed the paperwork, the Superior Court of California, County of Los Angeles, ordered both to share their financial information regarding all current income and expenses as well as property assets (owned both separately and together) and debts. The two have 60 days to comply.

The legal document likely protects Cuoco’s estimated US$100 million net worth. The actress, who started working as a child, has had an endorsement deal with Priceline for several years and was earning US$1 million per episode in the final two seasons of “The Big Bang Theory.” Celebrity Net Worth estimates her total income from the initial 12-season run to be just under US$150 million, and that’s before residuals for syndication and backend equity.

Cook, an accomplished equestrian, is assumed to have an impressive bank account to protect as well. He earns thousands in prize money at horse competitions every year, and his father is billionaire Scott Cook, founder of software company Intuit, which owns popular programs like TurboTax and QuickBooks.

The “Harley Quinn” voiceover actress was previously married to tennis player Ryan Sweeting for 21 months from December 2013 until their split in September 2015. The divorce was finalized the next year when Cuoco was ordered to pay the athlete US$165,000, plus US$195,000 for his personal trainers and up to US$55,000 in attorney’s fees. (SD-Agencies)
