The couple - who welcomed their first child, Sebastian Taylor Thomaz, in February - tied the knot secretly in a Los Angeles courthouse last month and plan to have a larger wedding this weekend.
A source told PopCrush the couple will host the ceremony at a country club in Wiz's native Pittsburgh.
In July, Wiz took to Twitter to share the happy news, writing: ''Me and Amber got married today. Weddings this fall. Thought I'd let yall know (sic).''
Wiz, 25 and Amber, 29, became engaged in March last year and Amber has been excited about it ever since.
She previously said: ''I think about it constantly. Like all day. No matter what I'm doing I always have my wedding on my mind. So I'm really excited.''
Meanwhile, the couple are completely besotted with their son and Wiz admitted he just spends his time trying to make Sebastian smile.
He recently told BANG Showbiz: ''He just kills us with his smile, we do whatever we can to make him smile.''
Amber added: ''Motherhood is amazing, I'm so happy. He's big, he's like the size of a six month old. The doctor says he's above average, he's going to be tall like the both of us.''
'Smalls Change (Meditations Upon Ageing)' arrives in April.
The two awards have made for a great 72nd birthday present for the country music icon.
