The Irish actor met Alicja Bachleda-Curuś on the set of movie Ondine in 2008, and they have one-year-old son Henry together. It has been claimed Colin called time on the romance after realising it was not working out, with Alicja said to have grown tired of waiting for the Hollywood star to pop the question.
"She realized that Colin is never going to marry her," a source told American magazine Star. "He cares for Alicja and the baby but he wants to be a free spirit."
Neither Colin, 34, nor 27-year-old Alicja have confirmed the reports.
