Kaley Cuoco, a former nationally ranked amateur tennis player, has hammed it up weekly as the female lead (and one of the highest paid TV actors) on CBS’ Big Bang Theory. The California girl got her start in commercials and modeling before making her acting debut in TV movie Quicksand. She’s always worked consistently — first with several bit parts (She played young Claire Danes in My So-Called Life and young Ellen DeGeneres on her sitcom!) and a few failed series and next as John Ritter’s daughter on 8 Simple Rules and as the voice of Bratz doll. Her Bang relationship bled into real life as she secretly dated Johnny Galecki for two years. After they split in 2010, the 2014 People’s Choice winner was briefly engaged to addiction specialist Josh Resnik and dated Superman Henry Cavill and musician Bret Bollinger. The Toyota and Priceline spokesperson married tennis player Ryan Sweeting in December 2013, less than seven months after they started dating.
