KALEY CUOCO of “The Big Bang Theory” has moved on from the clean-cut “Man of Steel” to a bad boy with an arresting past!

After a two-week romance with movie Superman Henry Cavill, the sitcom cutie is dating tennis pro Ryan Sweeting – who’s been busted on booze and drug charges.

Bahamian-born  Ryan was an 18-year-old freshman and top tennis player at the University of Florida when he was arrested in March 2006 for drunk driving and drug and alcohol posses­ sion in Gainesville, according to published reports.

After pleading no contest to the DUI, Sweeting was sentenced to probation and 50 hours of community service. His driver’s license was suspended for six months, and he was also slapped with a fine. The state’s attorney reportedly declined to pursue the drug charges.

“Kaley loves bad boys and then fact fact that Ryan has a criminal history really turns her on,” said an insider. “Henry was just too clean-cut and boring for her. She likes to date guys with a bit of an edge.”

Kaley, 27, cheered on her new beau – who’s ranked 518th in the world – during a match in Sherman Oaks, Calif., on Aug. 2. The two later shared a romantic lunch at Marmalade Cafe, followed by a spa session.

And 26-year-old Sweeting isn’t her first “bad boy.”

In March 2012, Kaley called off her engagement to Josh “Lazie” Resnik, a once-troubled heavy metal rocker who’s now an addiction specialist. As for her new romance, the source said: “While it’s still very early in the relationship, Kaley thinks she’s found the man of her dreams – criminal record and all.”
