Consider yourselves warned: The onetime Lusty Leprechaun is once again on the loose. People magazine reports that Colin Farrell is back on the market after an under-the-radar split several months back with actress Alicja Bachleda, whom he hooked up with on the set of "Ondine." News of their quiet bust-up comes about a year after they welcomed son Henry. Farrell, who is also dad to 7-year-old James with ex-girlfriend Kim Bordenave, "is not a guy who's interested in being tightly tied down in any relationship," a spy opines to the Chicago Sun-Times. Adds a source to Star, "He cares for Alicja and the baby, but he wants to be a free spirit." Free to enjoy himself maybe. The tab claims Colin was recently spied locking lips with model Agyness Deyn.
