Not so fun fact: they tied the knot just 21 months ago.
Us Weekly broke the news late Friday with People following shortly thereafter with a statement from the couple. The first evidence of their split came in the form of Kaley eliminating most instances of Ryan from her various social media accounts.
"Kaley Cuoco and Ryan Sweeting have mutually decided to end their marriage," Cuoco's rep told People once news of the breakup hit the web. "They ask for privacy at this time. No further statement will be issued regarding this matter."
The love story was in a different place as recently as April, when Cuoco took to Instagram in an effort to ease talk of trouble at home.
"I have never been more proud of anyone on this planet – this guy is fighting back from a whirlwind of injuries and not to mention constant 'conversation' regarding our marriage and basically any daily decision we decide to make," Cuoco shared with her fans.
If you're out of the loop - 29-year-old Cuoco and 28-year-old Sweeting, a tennis player, were engaged in September 2013 and married three months later, on December 31st, 2013.
