Jessica Biel says her healthy relationship with husband Justin Timberlake comes down to their respect for each other's careers and the mutual values they share.
The 35-year-old actress, who has two-year-old son Silas with the singer, says the pair are both dedicated to being ''selfish'' has allowed them to maintain a strong bond.
Speaking to Marie Claire magazine, Biel said: ''We have similar values; we believe in loyalty, honesty. We like to have fun. We like a lot of the same things.
''Also, in the business, we're all very career-oriented, and you have to be a little selfish. I understand that about my peers- about being focused and driven - and if you can find that and someone who shares the same values as you, it's like: Score!''
Biel also revealed how she has grown to be ''selfless'' since the arrival of their baby boy.
''You think you're a selfless person, and then you realise you're not. These little people come around, and they require so much, and your schedule is really not your own, nor is it important anymore, and it's very clear that it's your life now revolving around this dude.
''I'm not that person who feels like, 'Oh, my whole life changes for my kid,' but it does.''
Biel and JT married on October 19, 2012, at the Borgo Egnazia resort in Fasano, Italy.
