'Big Bang Theory' star Kaley Cuoco reportedly called off her relationship with Henry Cavill as she was overwhelmed by the intense scrutiny it was under.
The 'Man of Steel' star and Cuoco split up last month following a brief romance and friends of the actress say she found the interest in their relationship difficult to deal with, reported OK magazine.
"She just got overwhelmed with the very public Superman relationship. She's not used to that much attention and chaos in her life," a source said,
Cavill had split from actress Gina Carano earlier this year following a 10-month relationship, while Cuoco briefly dated musician Bret Bollinger after ending her engagement to Josh Resnik in March 2012.
Cuoco also previously dated her 'Big Bang Theory' co-star and on-off on-screen boyfriend Johnny Galecki for two years, but the pair managed to keep their relationship a secret for the duration.
She has now moved on to tennis player Ryan Sweeting and is much happier with this low-key romance.
"She thinks Ryan's a really hot, nice guy. It's nice that he's not really an industry guy," the source added.
