She is back to that itty-bitty body, but Nicole Richie is sure to put on a few pounds over the coming months as she's pregnant with her second child.

The couple opted out of "selling an exclusive" to the weeklies and instead fiancé Joel Madden posted the good news on his personal blog over the weekend, insisting that it was "better than winning an Oscar." Err, the "Good Charlotte" rocker knows that feeling?!

The couple welcomed their first child, daughter Harlow Winter Kate Madden, last year.

"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," Madden wrote.

Madden, 29, and Richie, 27, celebrated with a cozy breakfast together at Hugo's on Saturday morning before taking daughter Harlow to Cruz Beckham's fourth birthday party at Los Angeles Xtreme Martial Arts Center. Also in attendance was Cruz's brothers Brooklyn and Romeo as well as mama Victoria's BFF, Eva Longoria.
