Celebrity Week In Review: Jessica Simpson Pops, Ashton's Drama And More (PHOTOS)

It was a big baby week in Hollywood for celebrities as we kicked off May!

After what seemed like the world's longest pregnancy, Jessica Simpson finally welcomed her daughter, but she's not the only new celebrity parent. Maggie Gyllenhaal, J.R. Martinez and Marley Shelton all have newborns at home this week, and Backstreet Boy A.J. McLean announced this week that he's expecting his first child as well.

Here are some of this week's other noteworthy celebrity stories:
