The `Rehab` singer - who has turned her life around after overcoming battles with drink and drugs - is said to be "obsessed" with having children with her boyfriend Reg Traviss, who she has been in a relationship with for a year.
A source told Reveal magazine: "Amy`s obsessed with having children. It`s all she`s talking about right now. She is desperate to have a baby within the next year.
"Amy is doing everything she can to have kids. Because of the drugs and drinking, her body would not have been able to handle a baby. Now she`s on the road to recovery and is turning things around."
The 27-year-old hitmaker was thought to have been hugely upset when she heard her ex-husband, Blake Fielder-Civil, is due to have a baby with his girlfriend, Sarah Aspin, in May.
The source added: "She was devastated when she found out, and it made her even more determined to have her baby."
Amy`s father, Mitch, has previously admitted his daughter is broody, although he`s not sure she`s ready to settle down just yet.
He said: "She`s become so broody. She`s now at the age where she wants to have a baby. But I can`t see her settling down with 15 children just yet."
