Another one bites the dust.

Superman Henry Cavill and Kaley Cuoco have reportedly already split.

The Man of Steel actor and The Big Bang Theory actress have broken up, just days after the news broke of their relationship, PEOPLE reported.

Cavill and Cuoco remain friends after a few dates together, E! News reported.

Barely 48 hours after their venture into romantic territory came to light on July 1, they were spotted hiking and then spotted holding hands outside a Los Angeles-area supermarket.

Cavill split up with Haywire star Gina Carano earlier this year, while Cuoco briefly dated Pepper bassist Bret Bollinger after ending her engagement to Josh Resnik.

No reason has been given for the split.
