Rosa confirms that she expecting a baby Kardashian, but sadly had a miscarriage.

Shocker! All of us Khloe & Lamar fans were curious as to whether or not Rob Kardashian‘s ‘friends with benefits’ relationship with dancer Rosa Acosta really led to a pregnancy and now, we know! Rosa admits to Star magazine exclusively that she was pregnant with Rob’s baby!

“We’ve always been friends and flirty,” Rosa, 25, explains. After the first time they had sex, Rosa says, “I took a few pregnancy tests and they came out positive. I went to the doctor who said…the baby didn’t attach. Essentially, I had a miscarriage.”

But as unprepared as Rob, 25, was for fatherhood, Rosa says he stepped up to the task and was really supportive before finding out she lost the baby.

“I’m glad he was there for me as a friend and ready to step up as a dad,” she admits. Wow, what would Kris Jenner think?
