The 'Roar' hitmaker is hoping to get pregnant with her 36-year-old boyfriend and the pair are thrilled about the prospect of starting a family.
A source told Closer magazine: "Katy brought up the idea of having a baby a few weeks ago. He was really supportive and said he'd love her to be the mother of his child."
Katy, 29, is already said to be being cautious about her body during stunt when she performs live, such as when she appeared at the 2013 MTV Europe Music Awards in Amsterdam earlier this month, where she was suspended nine metres in the air.

The source added: "Their inner circle say it won't be long until there's happy news. She's already been taking precautions. Extra safety measures were taken during her EMA act, where she was suspended in the air. She didn't want to put her body under any strain."
Friends of Katy - who split from ex-husband Russell Brand in 2012 -are worried about her rushing into things, especially as John has previously dated Taylor Swift, Jessica Simpson and Jennifer Aniston and has a long list of failed romances.
The source explained: "Katy's pals are concerned she's too headstrong and won't factor in John's relationship history. But Katy says he'll make a great dad and believes a baby would only strengthen their bond."
