Pregnant Kourtney Kardashian stepped out in a very revealing dress to the New Year’s Eve bash with her boyfriend Scott Disick. The reality star revealed her ample cleavage in a sparkling black gown that had a plunging neckline, the high-slit dress also showed off her toned and tan legs. Although the 32-year-old star is three-months pregnant, she didn’t seem to be bothered at all in her very elegant and sexy Christian Louboutin heels. Meanwhile Scott looked dapper in a tuxedo. Kourtney hosted the night with Scott at Chateau Nightclub & Gardens at the Paris Las Vegas.
