Hurt Locker star Jeremy Renner says that fatherhood is the best thing he's ever done and that days spent away from his daughter are miserable.

The actor's ex-girlfriend gave birth to his daughter Ava in March 2013 and Renner told People magazine, "It's the best thing I've ever done. I like starting and ending my day with her. When I don't, life is quite miserable.

"I thought I like what I do for a living, but now I have this little wonderful creature, and she kind of squashes all of that. She's messed up my life in the most beautiful way possible. She takes all my love."
