Kim Kardashian promoted her perfume "Glam" at Kardashian Khaos in Las Vegas on Saturday at the Mirage Hotel and Casino. The reality star showed off her growing baby bump in a bright red sleeveless dress.

Kardashian is several months pregnant with her rapper boyfriend Kanye West's baby, which is due in July. While the media has been taking digs at the reality star for her weight gain, several celebrities have come out in her defense, including, most recently, Gloria Steinem.

Kardashian appeared in good spirits in Sin City despite having to deal with some court drama the previous day. On Friday, her estranged husband Kris Humphries didn't show up to a mandatory divorce court hearing.

The former couple was expected to meet in an attempt to put together a settlement before their case goes to trial on May 6. The Brooklyn Nets player failed to appear.
