Now it's the turn of Rachel Weisz and Britney Spears who are the latest celeb mums who have spoken about their desires to have another baby.
After watching fellow singer Beyonce take over the MTV Video Music Awards with her pregnancy announcement, Britney has revealed she too, is trying to have a baby with boyfriend Jason Trawick.
"[Britney's] always wanted a big family but also wants to prove to herself and to her family she is a good mother," a source told The Sun.
"Now she's finally had the green light from Jason, she can't wait," the source added.
We wonder what dad Jamie Spears thinks of this announcement? He reportedly "banned" her from having more children...
Meanwhile, The Mummy actress Rachel Weisz has been hinting that her son, Henry, may have a baby half-brother or sister in the future. Henry, 5, is Rachel's son with ex-partner and Black Swan director Darren Aronofsky. The 41-year-old actress then married James Bond actor Daniel Craig last June in a low-key ceremony. Daniel, 43, has a 19-year-old daughter, Ella, from his previous marriage.
"Oh I wouldn't make [a baby] just for the sake of giving my son a sibling," Rachel told Lucky magazine.
"But...you never know," she mysteriously added.
It is no wonder that Rachel may be feeling broody again - she recently revealed that being a mum has made her feel "so much sexier".
Will we be seeing a mini James Bond on the scene soon?
