Chris Pine, star of 2009's Star Trek, has just made the announcement that he has split from his model girlfriend Dominique Piek.

The 32-year-old Star Trek hunk and his model girlfriend made their red carpet debut as a couple at Cannes Film Festival last May, but aside from that single outing, Pine has kept his romantic life extremely personal.

Besides the statement of the couple's split, no juicy information about their relationship was given. So it remains a mystery why the pair of one year are calling it quits.

When E! News asked for a statmement, he politely declined.

The actor told Men's Health U.K. last year he's attracted to women with a sense of humor. "I do like dating cynics - they tend to be incredibly funny," he said. "Dating someone on the opposite end of the happy spectrum teaches you an incredible amount of patience."

Maybe the couple split up because she couldn't make him laugh. Even beauties can ge dumped if their personalties can not measure up!

Pine will reprise his role in Captain Kirk in the Star Trek sequel Star Trek Into Darkness this year.

Chris has also starred in the films The Princess Diaries 2: Royal Engagement (2004), Just My Luck (2006), Smokin' Aces (2007), Unstoppable (2010), and This Means War (2012).
