Well, that was short: Henry Cavill and Kaley Cuoco are no longer an item.
People magazine reports that the romance -- which the couple appeared to make official just last week by holding hands in front of the paparazzi -- has already ended, though a source told the publication "no reason was given" as to the split.
E! Online broke the news Thursday, saying that the British "Man of Steel" star, 30, and Cuco, 27, "remain friends after a few dates together. Cavill had reportedly been a longtime fan of Cuoco's television show, "Big Bang Theory."
Cavill recently broke up with his girlfriend of one year, "Haywire" actress Gina Carano.
