    What an interesting time to suddenly show off some very public displays of affection, Johnny Galecki.

    Nearly a week after ex-girlfriend Kaley Cuoco tied the knot to Ryan Sweeting, the Big Bang Theory star was spotted relaxing on the beaches of Mexico with his longtime girlfriend Kelli Garner. And the couple wasn't afraid to show just how crazy they are about each other to the paparazzi.

    Galecki, comfortable in his swim trunks, cuddled close to his ladylove while laying down on the sand, and made sure to steal a few kisses.

    The actor, who is usually very underwraps with his private life, secretly dated Cuoco for two years.

    In the October issue of CBS Watch! Magazine, Kaley opened up about dating Johnny, who was her real-life boyfriend while he played her onscreen boyfriend. "It was such a huge part of my life and no one knew about it," Cuoco tells the mag in an article accompanied by a steamy photo shoot. "It was a wonderful relationship but we never spoke a word about it and never went anywhere together."

    Regardless of the romantic history, Galecki told E! News at the L.A. premiere of CBGB that he's "very, very happy" for Kaley after hearing of her sudden engagement. "She's very happy, which makes me terribly happy," he said.

    Galecki wasn't surprised, however. "I don't think any of us in the cast make any sort of...I don't think we surprise each other anymore at all," Galecki said, laughing.
