Keeping herself busy as she readies for her second child, Nicole Richie was spotted running around Los Angeles over the weekend.

Wearing a casual pink ensemble, the former “Simple Life” starlet dropped by her Pilates class before grabbing a bite to eat at Sharky’s.

And while she’s already been down this path before, insiders tell that Miss Richie has been a bit emotional as of late.

“Her hormones have really been kicking in and Nicole has been crying at everything from movies, to TV shows and even commercials,” a source told press. “Joel [Madden]has been tiptoeing around her making sure he doesn’t upset her – but it doesn’t seem to be working.”
