Kim Kardashian Jeans: Pregnant Reality Star Trades In Her Usual Evening Wear For Casual Chic (VIDEO, PHOTO)

Pregnant Kim Kardashian was keeping it casual in jeans as she helped her sister, Kourtney, celebrate her upcoming birthday at a bowling party yesterday (April 17).

Wearing loose, light-colored, ripped jeans and a black T-shirt, the 32-year-old headed to the bash with family and pals in Los Angeles, Calif., and the girls posed up a storm throughout the night in several Instagram snaps. The whole family was out, with Kim being joined by her sisters Kourtney and Khloe, half-sisters Kylie and Kendall, her mom Kris Jenner and her brother Rob (Kanye was noticeably absent yet again, and Kourtney's man Scott Disick was reportedly there, though not in any of the photos).

The family decided to host Kourtney's birthday bash at a bowling alley, where the "Keeping Up With The Kardashians" star celebrated turning 34.

Kim, who had earlier showed off her pregnancy curves in a tight green dress, was seen in one picture with friends placing their hands on her growing baby bump.
