Hollywood actors Lauren Graham and Peter Krause didn’t exactly have the most romantic start to their relationship. Although they met way back in 1996, they eventually fell in love while playing brother and sister on the set of TV comedy ‘Parenthood’.

Nonetheless, the two of them have been inseparable ever since. Although they are yet to marry, Lauren has confessed her undying love for Peter. She once said, “My world became brighter. He made me understand life.”
