Celebrities talk motherhood

No matter what it looks like in the paparazzi pictures, celebrities don't necessarily have it easy when it comes to motherhood.

With Mother's Day being this weekend, CNN talked to a few stars about their takes on parenting.

Earlier this week, Jennifer Lopez talked about how her struggles with getting pregnant helped her relate to her character, who's waiting to adopt.  Now, some of her co-stars are talking about their experiences with kids.

In real life, Cameron Diaz doesn't have kids, but in her new film with Lopez, “What to Expect When You’re Expecting,” she plays a celebrity fitness trainer who's expecting a baby. In real life, she's the happy auntie to four kids, but she's open to having her own someday.

Her co-stars, Elizabeth Banks and Ben Falcone, play a married couple expecting their first child. Banks and her husband recently had a baby by surrogate, while Falcone and his wife, "Bridesmaids" star Melissa McCarthy, have two daughters.

Both actors talked about the funnier, tougher (and sleepier) side of having little ones.

Vanessa Williams, meanwhile, is on a book tour with her mother and co-author Helen. Her tome, "You Have No Idea," shares the story of the former beauty queen's life, and they each explain how they dealt with crises, both before and after Vanessa Williams entered the spotlight as the first African-American Miss America.

The "Desperate Housewives" star shares some advice on how to cope with adolescents who have decided mom isn't the the authority on anything.

Watch the stars give their takes on becoming and being parents.

“What to Expect When You’re Expecting,” which also stars Chris Rock,  Dennis Quaid and "Glee" star Matthew Morrison, arrives in theaters May 18.

Vanessa and Helen Williams' book "You Have No Idea" is available now.
