Pregnant Celebrities' Post-Baby Bodies: Before And After (PHOTOS)

Just one month after giving birth to Blue Ivy, Beyonce made her first post-baby public outing this week when her husband, Jay-Z, gave a concert at Carnegie Hall.

Bey's much-buzzed-about outings -- she stepped out not once, but twice this week -- set the bar mighty high in terms of stunning everyone with a post-baby comeback, but she's not the only one to shine after becoming a mom.

Victoria's Secret model Miranda Kerr looked better than ever when she stepped out just eight weeks after giving birth to son Flynn last year, as did Jessica Alba, who was absolutely glowing when she showed off her figure less than a month after giving birth.

As for all new moms, it can be a struggle for celebrities to get back into pre-pregnancy shape -- although we're sure it's helpful to have a personal trainer and chef to help the process along.
