Justin Timberlake thinks marriage is a ''team effort''.

'The Trouble With The Curve' actor - who is gearing up to wed his girlfriend of five years Jessica Biel - is determined to have a marriage as successful as his mother and stepfather's and believes a happy relationship is based on give and take.

Justin mused: ''I think it's important to remember that you go into something like marriage knowing that you don't know very much about it at all.

''But I do look at the marriage of my mother and stepdad, and what makes it work for them is that it's a team effort.''

The former 'N Sync singer - who has previously romanced Britney Spears and Cameron Diaz - admitted living with Jessica isn't always easy, but when they go through a rough patch he tries to channel his stepfather's qualities of patience and compassion.

Speaking at a recent press conference with the Hollywood Foreign Press, Justin added: ''Some days are better than other days for all of us - and if we have our good days and bad days individually, and then we're dealing with someone else's good and bad days on top of that, it's going to add up.

''My mother is a ball of fire in the world and I love that about her. But what I have learned from my stepdad is something as important, which is patience and compassion.

''Because when you are living with someone else, those two qualities go a long way.''

When asked what makes Jessica wife material, the 31-year-old star grinned: ''She's a really, really, really special person. Plus, she's really, really, hot!''
