Colin Farrell could be expecting a baby with his girlfriend Alicja Bachleda.

The 'In Bruges' actor and the stunning Polish model - who have been dating since earlier this year - are believed to be starting a family together after she was pictured with what appeared to be a growing baby bump at Los Angeles International Airport 'LAX' on Sunday (16.08.09).

An onlooker said: "Alicja was glowing. I couldn't help but notice her rounded stomach, which was only enhanced by a clingy black top. She was resting her hand protectively on her tummy as they made their way through the airport."

A representative for the 33-year-old screen heartthrob is yet to comment on the reports.

If the baby rumours are true, it will make Colin a father for the second time.

Colin - who is known for his womanising ways - already has a five-year-old-son James Padraig from his relationship with model Kim Bordenave.

The actor asked Alicja to move into his Hollywood Hills mansion in May so he could spend more time with her.

At the time, a source said: "Colin wants to be with her all the time. He loves knowing she'll be waiting for him when he comes home."

Colin and Alicja met last year while filming 'Ondine', a movie about an Irish fisherman who finds a mermaid trapped in his net.
