Justin Timberlake's marriage to Jessica Biel will ''bring out the best'' in him.
The 'Bad Teacher' actor's former *NSync bandmate Joey Fatone believes the 31-year-old star will be an ideal husband because he always gives whatever he does 100 per cent of his focus and attention.
He said: ''Not much is going to change. He's a great dude and he's very focused on what he does and everything else, and I'm sure this will bring out the best.
''He's been with her for a long time, so it's basically a piece of paper. That's what me and my wife Kelly Baldwin were like and we've been together over 18 years now.''
Giving his advice for married life, Joey urged Justin to make sure he made the most of their time together because it goes by so ''quickly''.
He told People.com: ''Just enjoy life, because it goes by way too fast. Look, I have an 11-year-old and a 2-year-old, and that just shows how quickly it goes.
''It's communication that really needs to drive that relationship. Keep it happy, light and fun.''
