Kaley Cuoco’s Dating History: From Johnny Galecki and Ryan Sweeting to Karl Cook and More

From costar romances to divorces, Kaley Cuoco’s love life has been making headlines for years.

Cuoco wed Ryan Sweeting in 2013, but the two called it quits after 21 months of marriage. Following the split, the actress went on to date Paul Blackthorne and Henry Cavill before wedding Karl Cook in 2018.

Three years into their marriage, however, the couple called it quits.

“Despite a deep love and respect for one another, we have realized that our current paths have taken us in opposite directions,” the Flight Attendant star and Cook said in a joint statement in September 2021. “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.”

She began dating Ozark alum Tom Pelphrey in 2022, and the pair welcomed their daughter Matilda the following year. Pelphrey popped the question to Cuoco in August 2024.
