The 26-year-old star, who already has a 5-month-old daughter, Harlow, with boyfriend Joel Madden, is reportedly expecting a second child, according to FemaleFirst.
It seems that Richie has decided to give her daughter a new companion. A source said, "Nicole is dying to have a sibling for Harlow who is close in age. She doesn’t want them to be more than two years apart, so that they can be best friends forever."
The pregnancy rumours sparked when Richie was seen wearing a maternity-style top, which isn’t something she normally wears.
