It's official: The Kardashians are having a baby line.

Sisters Kim, Kourtney and Khloé announced yesterday they will launch a collection for baby girls up to 24 months, exclusively at Babies"R"Us.

The line, called Kardashian Kids, will feature basics such as onesies and caps, as well as two-piece sets, jackets and dresses, with butterflies, stars and animal prints prevalent. The items will cost between $15 and $30 and will be available in stores and online starting March 15.
