Nicole Richie has sparked speculation that she is pregnant for the second time.

The 26-year-old was spotted wearing a maternity-style top while walking in Hollywood, fuelling rumours that she is expecting a sibling for six-month-old daughter Harlow Winter.

Richie is rumoured to want another baby in the near future so she can have children of a similar age.

An onlooker told OK!: "She ordinarily goes for tight T-shirts and vest tops."

Richie's partner Joel Madden recently denied that the pair have plans to marry.
