The answer is none of the above as the actor is presently single. Meanwhile, the person that has come closest to becoming Colin Farrell’s wife is Amelia Warner. Also known as Slow Moving Millie, Warner is an actress, singer, songwriter, and composer. She has released several singles as well as a full-length album. She has also won several awards including the award for Breakthrough Composer of the year at the 2018 IFMCA Awards.
Farrell and Warner first met at a movie premiere in 2000. They dated from 2000 to 2002 during which they tied the knot in a non-binding ceremony in Tahiti. They subsequently broke up four months after the ceremony and went their separate ways. Warner has since moved on with her life. She is married to Fifty Shades of Grey star, Jamie Dornan, and they have three kids together.
