The Wedding Crashers star has long enjoyed a bachelor's life, dating Jennifer Aniston for a year in 2006 before meeting and proposing to real estate agent Weber earlier this year (09).
And the 39 year old is finally ready to settle down - insisting his relationship with Weber has made him realise he wants to have children.
He tells People.com, "It's the first time that I really want to have kids.
"I've been very fortunate in my career, and my life has been about that for so long that you get bored of it. You're ready for your life to be about other people and other things."
