It’s been a whirlwind couple weeks for Big Bang Theory star Kaley Cuoco and Man of Steel’s Henry Cavill, as they made their debut as a couple last week but have reportedly already split.

Just last week, they seemed to confirm a rumored relationship by stepping out holding hands in Los Angeles. Before that, they were seen hiking and getting sushi and going to a supermarket together.

A source has confirmed to People that they’ve already decided to break up, but no reason was provided for the sudden split.

It’s now said Cuoco, 27, and Cavill, 30, were only in the "beginning stages" of a relationship and they apparently decided it wasn’t for them, although sources said last week they were “totally hot for each other.”

Cavill just recently split with girlfriend Gina Carano in May. Cuoco most recently dated Pepper bassist Brett Bolinger after calling off her engagement to Josh Resnik. She dated her Big Bang Theory co-star Johnny Galecki for two years.
