Colin FarrellColin Farrell has revealed he entered rehab seven months ago for the sake of his three year old son, James.

Colin cited exhaustion and an addiction to prescription painkillers when he entered rehab but was also known to have problems with alcohol and illegal drugs.

He told the Daily Mirror: “I was burning the candle at both ends and the flames met in the middle. It just caught up with me. It was a long time coming but I had my arse handed to me on a plate. Now I haven’t had a drink for six months.”

“For the first time, I got to step back and have a look at the life I had created.”

“I thought about what I wanted to do and got to take the metaphorical deep breath I needed. It did me good.”

“I wasn’t suicidal but I never had much of a will to live a long time.”

“Now I want to watch my son grow up, be his friend and his father, and hang around with him. So he’s the greatest priority in my life.”

But Colin has no desire to reunite with James’ mother, Colin’s ex-girlfriend Kim Bordenave. In fact, despite rumours of a relationship with actress Lake Bell, Colin is happy to be single for the time being: “I don’t have a better half or significant other. I’ve found a love I never thought I’d find with my son.”

“And with my life as it is now, it would be very hard to have somebody - for them and me. I’m never in one place for longer than three or four months and have been living in hotels for seven years.”

“Plus, I find that the work takes a certain amount out of me and as much as it would be nice to have somebody to pick me up a little bit, sometimes I just want to be on my own with my own thoughts. I’ve been lucky enough to have been in love a few times and I’ve felt how wonderful it is. But it comes with a lot of responsibility and pressures.”

“It’s better for me, at 30, to be on my own.”
