Kaley Cuoco and Ryan Sweeting's Relationship Timeline: A Look Back

While some couples like to take things slow, actress and producer Kaley Cuoco and former tennis pro Ryan Sweeting did the opposite. 

After first meeting in August 2013, Cuoco and Sweeting got engaged the next month and wed in December of that year. Like other couples in whirlwind courtships, The Flight Attendant star and her beau couldn't keep their hands off each other — whether on the red carpet, at the beach, or sitting courtside at a Lakers game.

Our favorite PDA moment, however? When they made out at Craig's in West Hollywood during a triple date with Haylie Duff and her then-boyfriend Matt Rosenberg and Ali Fedotowsky and her husband Kevin Manno (the other two couples were also kissing). Needless to say, it made for a great photo that Cuoco shared in a now-deleted post on Instagram, per E! News.

However, just as fast as Cuoco and Sweeting's romance took off, it quickly ended. By September 2015, the couple split and filed for divorce after nearly two years of marriage. The Based on a True Story actress moved on, marrying her second husband, Karl Cook, in 2018 before their separation in 2021 and divorce in 2022.

Since her split from Cook, she has been enjoying parenthood and date nights with fellow actor and partner Tom Pelphrey, whom she welcomed daughter Matilda Carmine Pelphrey with in March 2023. Amazing how much can change in a decade, right?
