The Irish actor Colin Farrell has sparked rumours of a secret marriage after being seen wearing a ring on his wedding finger.

The star was seen wearing a band on the third finger of his left hand while passing through a US airport.

He had made no effort to hide the ring while at LAX Airport in Los Angeles with his girlfriend Muireann McDonnell.

He didn’t seem to be hiding the ring. Maybe he has finally found the girl he wants to settle down with, an onlooker said. He has been dating Muireann since early last year.

Colin has a four-year-old son called James with ex-girlfriend Kim Bordenave.
