They reckon Madonna's children Lourdes, six, and Rocco, two, will have a new brother or sister later this year.
The magazine has put together loads of reasons why they reckon the music star - married to film director Guy Ritchie - is pregnant:
- Madonna and Guy have moved to Los Angeles, where she thinks its best to have a baby.
- She's started wearing baggy tracksuits.
- She's stopped dying her hair, because hair dye could hurt the baby.
- The photos for her new album were taken last year, before her bump started showing.
There have been rumours for a while that 44-year-old Madonna is expecting again.
And with this latest news those rumours are sure to start again.
