Amy got hitched to 24-year-old Blake Fielder-Civil in a low key Miami ceremony last Friday, but plans for a girl's night out are only now being made.
According to The Daily Mail, Amy remained tightlipped about her big day, but did wink at reporters when she was asked if she had gotten hitched.
And Blake has even changed his MySpace status from single to married.
Pal Kelly Osbourne told The Sun Amy was planning a post-wedding hen do for all her friends.
Speaking to The Sun Kelly said: "I have spoken to Amy on the phone and she is so happy. Just looking at them together you can tell they are so in love. They are soulmates - anyone can tell you that.
"I had no idea they were getting married, none of us did. The wedding was a very small thing, Amy hates a lot of fuss."
