That's pretty huge news, right?!
Nadiya made the announcement while on ITV's Loose Women, revealing she was told the news a couple of weeks ago.
Nadiya will be serving an orange drizzle cake with orange curd and orange buttercream, and it will be personally delivered to the Queen next Thursday on her 90th birthday at Windsor Castle's Guildhall.
Revealing the news, Nadiya said the cake would be "very citrusy", and said her children initially thought she was baking a cake for Mary Berry!
Nadiya said: "When I told the kids [I was making a cake for the Queen], the boys were great at keeping it a secret. I told my daughter and she said, 'Oh Mary Berry? You've made lots of cakes for Mary Berry.'"
Nadiya won GBBO last year, and the grand finale was a ratings hit with 14 million people tuning in.
