Is Victoria Beckham getting ready for another baby?

The 40-year-old and her soccer star husband David already have sons Brooklyn (15) Romeo (11) and nine-year-old Cruz and daughter Harper together.

However, as there is a substantial gap between the three-year-old Harper and youngest boy Cruz, nine, Victoria is said to be thinking of adding a new addition to the family.

"Victoria's been saying she doesn't want Harper to feel like an only child - the boys are all very close. It would be lovely for her to have a little brother or sister so she can experience the closeness they've had growing up together," a source told Closer magazine.

"Victoria knows the boys will always look out for Harper, but she also knows how special it is to have a sibling close in age. Victoria and David had a heart-to-heart on Harper's birthday recently and she admitted she's been coming round to the idea of a fifth child. David was surprised but very happy."

While the dream may be there, the brunette beauty is said to fear the prospect of becoming a parent again at a later age. There's also the attention which needs to be given to her eponymous fashion label, as well as David being busy in Miami building a new soccer franchise.

"Vic is concerned about having a baby in her 40s and being an older working mom. She's committed so many hours to her new projects - she's trying to juggle everything and it's exhausting," the insider added. "But David has promised to be hands-on so she can still focus on her career."
