The two had only been in the "beginning stages" of a relationship as it was.
The new couple alert was announced at the start of July. A couple of days later, they were photographed hiking and then holding hands at the grocery store. Kaley was also seen getting coffee for two a couple of times. And then ... nothing.
Maybe they couldn't handle all the attention. Or maybe they just realized they didn't have that spark together, like any other couple that goes on a couple of dates and then decides it's not working.
In August 2012, it was announced that Henry and his fiancee Ellen Whitaker had ended their engagement. Before Kaley, he dated Gina Carano. Kaley dated Bret Bollinger after ending her own engagement to Josh Resnik. Some tongues wagged that this new Henry/Kaley romance was just for PR. But if that were the case, wouldn't they have extended it beyond a couple of weeks?
Whatever happened, the silver lining is that Henry Cavill is apparently back on the market!
