Actress Anne Hathaway wants moms everywhere to know that it's OK to gain weight during pregnancy, and it's also OK if you don't lose that weight quickly after giving birth.

"There is no shame in gaining weight during pregnancy (or ever)," the 33-year-old actress captioned a photo on Instagram. "There is no shame if it takes longer than you think it will to lose the weight (if you want to lose it at all). There is no shame in finally breaking down and making your own jean shorts because last summer's are just too dang short for this summer's thighs. Bodies change. Bodies grow. Bodies shrink. It's all love."

Hathaway gave birth to her son, Jonathan Rosebanks, with her husband, Adam Shulman, in March.
