Actress Kaley Cuoco has moved on from her failed engagement and is dating rocker Bret Bollinger, according to a report.

The Big Bang Theory star became engaged to Josh Resnik in October, but the couple called off the wedding plans earlier this year.

Cuoco was spotted out with a mystery man on St Patrick's Day, and now E! News has identified her suitor as Pepper frontman Bollinger.

The pair was snapped kissing courtside at a Los Angeles Lakers home game on Friday, and also cuddled up to take photos of themselves on the star's iPhone.
