Though Kim Kardashian recently blasted MTV's "Teen Mom" for glamorizing teenage pregnancies, Rosie O'Donnell is defending the series, saying it sends a positive message to young girls.

"My daughter is 13. I watch it with her," O'Donnell, a mom of three, tells Us Weekly. "The rate of teenage pregnancy is up, so when my daughter saw that ['Teen Mom 2'] was on the air, I said 'Let's watch it.'"

O'Donnell, 48, believes the show doesn't sugarcoat young motherhood but instead reveals the harsh realities.

Though she seems to have it all—fame, fortune and a happy marriage—fun-loving reality star Khloe Kardashian admits that she has her struggles like everyone else, especially when it comes to body image.

"My weight is always going up and down. I'm always fighting that, and I feel like no matter what I do, I never look good enough to everybody else," Kardashian, 26, admits in a video Q&A on her blog. "But that's been a struggle that I think I've gotten a hold of, not caring what other people think. Now I just have my body to how I like it."

Despite feeling more comfortable in her skin, Kardashian says she isn't immune to being constantly compared to sisters Kim, 30, and Kourtney, 31, and the speculation that she's pregnant any time she puts on a pound.

"Other people's words eventually do come and hit you hard," she says. "My weight is my biggest lifetime struggle. It's not the biggest thing in life, but it does get you down sometimes."
