Kaley Cuoco Dating 'Man of Steel' Star Henry Cavill, Sources Reveal

Reports are swirling that Kaley Cuoco and Henry Cavill are the newest celebrity couple after sources close to the stars said that they are both enjoying getting to know each other in the wake of the new Superman movie "Man of Steel."

Cuoco, who plays Penny on CBS's hit sitcom, "The Big Bang Theory," set off the new rumor after she tweeted a picture of her in front of a "Man of Steel" poster.

"Everyone go see "man of steel". It's fantastic in every single way," the actress tweeted.

A source close to the couple also revealed that the two have been together only a short while.

"They were both single and started dating recently," a source close to the new couple told People on Monday.

"It's just the beginning stages of a relationship and they're having a great time," the source added.

The extra promotion may be paying off for the film at the box office after it was revealed the movie broke the record for a June debut.

"Man of Steel" produced a record-breaking $125 million during its debut at the North American box office.

The studio rolled out "Man of Steel" in 4,207 theaters and took in an average of $29,731 per-location. It also helped that 3,350 of the screens were 3D and Imax, with many moviegoers opting to pay premium prices for "Man of Steel." Forty-one percent of the gross earnings came from 3D, which includes 12 percent from Imax. The Imax screens brought in $13.3 million, averaging $40,181 per location, also a June record.

This was the first Superman movie in seven years and "Man of Steel" did not disappoint. The movie recorded the biggest opening by any movie in June, and its debut tops the openings of the previous five films in the franchise combined.

The strong showing allows Warner Bros. the ability to create a new franchise based on those superheroes and villains, in the same way Disney has done with its Marvel Comics characters such as "Iron Man" and "The Avengers."
