For the first time ever, Pine, 31, and his Sports Illustrated model girlfriend, 26, walked hand-in-hand at the opening night gala in France Wednesday. South African Piek, who wore a Giorgio Armani gown, tweeted that "nothing could have prepared me for the crazy red carpet experience. Thank goodness I made it in one piece up the stairs!"
Pine -- whose exes include Olivia Munn, 31, and Audrina Patridge, 27 -- began romancing Piek last fall. In November, the Star Trek actor visited Piek's native country and "stayed with her parents in Capetown," a source tells Us Weekly. "Dom introduced him to all of her friends and family there."
Prior to her relationship with Pine, Piek -- who resides primarily in New York City -- dated professional baseball player C.J. Wilson, 31.
