Kaley Cuoco and Henry Cavill break up after 12 days

Kaley Cuoco and Henry Cavill ended their short-lived romance only 12 days after the world found out they were dating in the first place.

According to People magazine, no reason was given for the split though a source did say that the "Man of Steel" star and the "Big Bang Theory" beauty were only in the "beginning stages" of their relationship.

Ever since news broke of their relationship, Cavill, 30, and Cuoco, 27, became the paparazzi's favorite couple. In the following week and a half the two were spotted hiking, going on a sushi date and doing grocery shopping.
