Washington, Feb 23 : American socialite Nicole Richie and her boyfriend Joel Madden are expecting their second child, if reports are to be believed.

Just a year after the birth of their daughter Harlow Winter Kate Madden on January 11, Madden, 29, is said to have written about it on the website of his band Good Charlotte.

The message titled `Better than winning an Oscar!' suggests that Madden is very excited.

"I am so happy to tell everyone that Harlow is going to be a big sister! God has truly blessed my family. Hope [you''re] all feeling as good as i am right now," People magazine quoted him as having written.

Richie, 27, whose wild childhood is well documented, has given credit to the birth of her daughter Harlow for the more tranquil life at home she now leads.

"She gives life a whole new meaning," Richie said in a cover story featuring photos of the blissful family.

There have not been any comments on the second pregnancy from their representatives. (ANI)
