Colin Farrell quietly split from his actress girlfriend Alicja Bachleda several months ago, a source confirms to our friends over @PEOPLE.

The two are parents to a son Henry Tadeusz Farrel, who was born last year. Farrell is also dad to 7-year-old son, James, with model Kim Bordenave.

Bachleda, 27 and Farrell, 34, met on the set of last year's Ondine, which they costarred in. At the premiere, Bachelda told our friends over @PEOPLE of their romance: "We were very professional and focused on our part and our jobs. The story itself is so beautiful … we really didn't have time to get our true emotions [on screen]."

Farrell's camp had no comment on the split. The actor has been busy filming back-to-back movies recently.
