Actress Liv Tyler says it's difficult to perfectly balance family and work and that one will always suffer at the expense of the other.

The 36-year-old, the daughter of Aerosmith frontman Steven Tyler, raises 10-year-old son Milo with ex-husband Royston Langdon, reports contactmusic.com.

"The life of your family possibly won't flourish as it might. But when you focus on your family and you put that first, then your career suffers in some sort of way. I can live with the career part not going so well, I think, but I don't think I could live with my family not,` she added.
