Irish actor Colin Farrell has proved just what a gentleman he can be - by buying his pregnant girlfriend a plush Hollywood home.

The 26-year-old Minority Report hunk recently announced he and model KIM BORDENAVE are set to have their first child together. And pals say he's making sure she's very well provided for.

A source says, "He bought her a very expensive place in the Hollywood Hills."

Before Farrell's big gift, Bordenave reportedly lived in a sparsely decorated, modern, wooden guest house in the back of another person's Los Angeles property.
