Henry Cavill and Kaley Cuoco's relationship ended just as quickly as it began. After Us Weekly broke the news of their pairing on Monday, July 1, a source close to the couple confirms that the Man of Steel actor and the Big Bang Theory star have agreed to split. "Things fizzled as quickly as they heated up," the source says. "They are still friends."

The actors first met at a Hollywood party in June. "He was nervous," an insider said of Cavill, 30. "He's always wanted to date her." After his 10-month relationship with actress Gina Carano fizzled in May, the sexy Brit decided to ask Cuoco if she was single. His timing was impeccable, as Cuoco had also recently come out of a relationship with musician Bret Bollinger.

After their coupling was revealed, the actors were spotted hiking in L.A. on July 2. The following day, they were photographed running errands at BevMo! and Gelson's Market in Studio City, Calif.

E! News first reported the couple's breakup.
